	* INSTALL:
	Mentioned problems with the Tru64 make and other minor changes.
	[2.2 branch]

2005-09-17  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* configure.in: [2.2 branch]
	Fixed the GMP linking test: replaced __gmp_version, which corresponds
	to a variable, by __gmpz_init (suggested by the GMP documentation),
	which corresponds to a function, as the auto tools assume the symbol
	corresponds to a function. It was failing with the AIX linker.

2005-09-16  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* zeta.c: Better initial precision. [2.2 branch]

	* const_euler.c:

	Fixed stupid bug (coth was computing 1/tan instead of 1/tanh).
	[2.2 branch]

	* mpfr.texi: Propagated the changes from the trunk to the 2.2 branch:
	- documented the mpfr_get_f and mpfr_pow_z functions;

	(concerning >> BITS_PER_MP_LIMB); some other small improvements.

	* round_p.c, tests/tcan_round.c:
	No longer assume that a mp_limb_t fits in an unsigned long (this
	is not true under IRIX, where a mp_limb_t has 64 bits and a long

	to stderr instead of stdout.

2005-08-23  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* set_ld.c: This was wrong. Let's do it even more like the 2.1 branch.

	* set_ld.c: Patch 1.25 didn't work under OSF1 with cc. Let's do it like
	the 2.1 branch (it now does work under OSF1 with cc).

	* get_ld.c, mpfr-impl.h:
	Updated mpfr_get_ld: removed useless and non-portable hacks, fixed
	bugs, and slightly changed the behavior for the x87 extended format
	(we shouldn't return long double's with more precision than really

	the problem for Visual C++). If IEEE 754 is not supported, one
	should probably use the standard INFINITY macro instead of
	(1.0/0.0), since (1.0/0.0) is specific to IEEE 754.

	* acinclude.m4, tests/tests.c:
	Applied patch by Steve M. Robbins for non-IRIX MIPS systems
	(originally for MPFR 2.0.3).

	* configure.in: Improve ICC CFLAGS by removins meaningless warnings.

	* strtofr.c: Remove some warnings on some "psycho" systems.

	  + spelling mistakes
	  + consistency: in direction @var{rnd} -> in the direction @var{rnd}
	  + @code{NULL} pointer -> null pointer (as in the C standard)
	  + in the example for mpfr_inits2 / mpfr_clears: NULL -> (void *) 0
	    as NULL isn't necessarily a pointer.

2004-10-18  Patrick Pelissier  <Patrick.Pelissier@loria.fr>

	Major update of the function mpfr_rint, including a small semantics
	change to behave like the C function rint (unless the result is not
	representable); as a consequence, mpfr_round now calls mpfr_rint with
	the NEAREST_AWAY internal (to rint.c) rounding mode. Manual updated
	to reflect this change.

2003-10-17  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* erf.c, tests/tasin.c, tests/terf.c, tests/tgamma.c, tests/trint.c:

	* tests/reuse.c: removed #define DEBUG (turned on accidentally)

2003-10-15  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* BUGS:
	Bug on the ternary value was fixed by Paul Zimmermann on 2003-10-14.

2003-10-14  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* mpfr.texi: added preamble about ternary flag for special functions

	* tests/reuse.c, tests/tacos.c, tests/tagm.c, tests/tasin.c, tests/tatan.c, tests/terf.c, tests/texp.c, tests/tgamma.c, tests/tgeneric.c, tests/thypot.c, tests/tzeta.c:

	replaced mpfr_can_round (approx, err, rnd1, GMP_RNDN, prec)
	by       mpfr_can_round (approx, err, rnd1, GMP_RNDZ, prec + 1)
	which in addition guarantees a correct inexact flag

	* TODO: added new items (version number, rounding modes)

	* README.dev: added comment about --enable-alloca=debug

2003-10-13  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* round_prec.c: fixed comment of mpfr_round_raw_generic

	* add1.c, extract.c, get_si.c, get_ui.c:

	used only in functions init, set_prec, round_prec)

	* tests/tadd.c: fixed bug in allocation for in-place operation

	* asin.c, atan.c:
	inexact flag should now be correct for directed rounding

	Clearer mpfr_eq documentation (thanks to Kevin Ryde for the remark).

2003-10-03  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* mpfr-impl.h:
	MPFR_ASSERTN rewritten to avoid "statement with no effect" warnings
	with gcc when the assertion is always true.

	* add1.c:
	Optimization (thanks to Patrick Pelissier), as the allocated size
	may be larger than the size used by the significant bits.

	* mpfr.texi, INSTALL: Updated installation notes.

	* cmp_abs.c, mpfr.texi:
	Infinities are now accepted in mpfr_cmpabs. Updated its definition
	in the source (no longer sign(abs(b) - abs(c))).

2003-10-02  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* mpfr.texi: Use @url{} for URLs.

	* mpfr.texi: As suggested by PZ:
	  o documentation of mpfr_fits_* functions moved to the section
	    on conversions;
	  o grouped some mpfr_pow special cases;
	  o explanation concerning the meaning of rnd in mpfr_frac.

	* tests/tset_str.c, tests/tset_z.c, tests/tsinh.c, tests/tsqrt.c, tests/tsub.c, tests/ttanh.c, tests/tui_pow.c, tests/tui_sub.c, tests/tzeta.c, tests/tmul.c, tests/tmul_ui.c, tests/tout_str.c, tests/tpow.c, tests/tset.c, tests/tset_d.c, tests/tlog.c, tests/tlog10.c, tests/tlog1p.c, tests/tlog2.c, tests/texpm1.c, tests/tfma.c, tests/tget_str.c, tests/thypot.c, tests/tadd.c, tests/tadd_ui.c, tests/tagm.c, tests/tasinh.c, tests/tatan.c, tests/tatanh.c, tests/tcan_round.c, tests/tcmp.c, tests/tcmp2.c, tests/tcos.c, tests/tcosh.c, tests/tdiv.c, tests/tdiv_ui.c, tests/terf.c, tests/texceptions.c, tests/texp.c, mpfr.h, mpfr.texi, print_raw.c, set_str_raw.c, tests/tacosh.c, BUGS, mpfr-impl.h:
	Updated documentation. In particular, mpfr_set_str_raw renamed
	as mpfr_set_str_binary. This function and mpfr_print_binary are
	now internal functions. mpfr_print_binary no longer prints the
	non-significant 0 bits. Updated the source to match the manual.
	mpfr_print_binary has been completely rewritten (now directly
	prints to stdout, without using an intermediate string). In
	mpfr_set_str_binary, replaced atol by strtol + error checking.

2003-10-02  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* mpfr.texi: added paragraph on support/grants
	added help for mpfr_erf

2003-10-02  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* mpfr.texi:
	Make node titles match section titles, and updated menus and xrefs.
	Added a line break after @samp{uninstall}.

2003-10-01  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* TODO, const_log2.c, const_pi.c, mpfr.h, mpfr.texi, zeta.c:
	Corrections in the MPFR manual (PZ & VL). Functions mpfr_const_pi,
	mpfr_const_log2 and mpfr_zeta now return a ternary value. Updated
	TODO file.

2003-09-30  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* BUGS: Added a bug related to the ternary value and worst cases.

	* pow_si.c, pow_ui.c: Added exponent range support.

	* mpfr.texi: Corrections up to Section 5.6 (PZ & VL).

	* get_z_exp.c:
	Re-added the assert on the exponent, but replacing MPFR_EMIN_MIN by
	MP_EXP_T_MIN (this makes more sense): an assertion failed would mean
	that the exponent is not representable (an undefined behavior in the
	ISO C standard). If need be, we could choose to return MP_EXP_T_MIN
	in such a case, or perhaps MP_EXP_T_MAX to signal an error. The
	mantissa would still be meaningful.

2003-09-30  Patrick Pelissier  <Patrick.Pelissier@loria.fr>

	* TODO: Update TODO & mpfr_set_prec.

2003-09-29  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	Removed mpfr_inits, mpfr_inits2, mpfr_clears from the documentation.
	Moved their prototypes to mpfr-impl.h (internal functions until
	decided otherwise).

2003-09-25  Patrick Pelissier  <Patrick.Pelissier@loria.fr>

	* const_log2.c, const_pi.c, generic.c, atan.c:
	Modify 'r' arg of GENERIC from int to long (min 32 bits).

2003-09-25  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	mpfr_lessequal_p, mpfr_lessgreater_p, mpfr_equal_p, mpfr_unordered_p.

	* TODO, tests/tnext.c:

	* mpfr.texi: Added information on special values for mpfr_pow.

2003-09-24  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* Makefile.am:
	added MAKEINFOFLAGS = --enable-encoding to get 8-bit characters in mpfr.info

	* AUTHORS, mpfr.texi: used ISO-8859-1 in AUTHORS
	and @`e, @"o in mpfr.texi (waiting for code for ISO-8859-1 compatibility)

2003-09-24  Kevin Ryde  <user42@zip.com.au>

	* acinclude.m4 (MPFR_C_LONG_DOUBLE_FORMAT): Remove conftest* temporary
	files.

2003-09-24  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* TODO: Removed

	- allow the ISO C "P" exponent separator for base 16 in input functions

	(already done).

	* TODO, tests/tset_ld.c: Implemented the following:
	- use (LDBL_MAX/2)+(LDBL_MAX/4*LDBL_EPSILON) instead of loop in tset_ld
	       to get largest power of 2 that fits in a long double

	* sub1.c: Added some MPFR_ASSERTN and improved a comment.

	* tests/texp.c, tests/tget_str.c:
	Avoid string literals longer than 509 characters (ISO C89 limit).

	* tests/texceptions.c (test_set_underflow, test_set_overflow):
	Cleaner fix (for pre-C99
	compilers).

2003-09-22  Kevin Ryde  <user42@zip.com.au>

	* tests/texceptions.c (test_set_underflow, test_set_overflow): Use
	"static" on "r" to allow non-constant initializers.

2003-09-21  Kevin Ryde  <user42@zip.com.au>

	* mpfr.texi (Converting Floats): In mpfr_get_d_2exp, the rounding mode
	is given, it doesn't use the default mode.

	* mpfr.texi (Assigning Floats): In mpfr_set_str and mpfr_set_str_raw,

	* mpfr.texi (Assigning Floats): In mpfr_set_*, remove remarks about
	long being rounded (this should be clear already), about rounding of
	decimal double constants like 0.1 (too basic to appear here),
	(Converting Floats): In mpfr_get_d_2exp, remove remark about exp
	exceeding IEEE exponent range (should be clear already).

2003-09-19  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* TODO: updated items: removed conversion from/to float (obsolete)

	* TODO, zeta.c: got rid of <math.h> dependency in mpfr_zeta

	* tests/tround_prec.c, tests/tzeta.c, round_prec.c, tests/tacos.c, tests/tasin.c, tests/texp.c, tests/tgamma.c, exp_2.c, get_str.c, log_b2.h, mpfr.h, mpfr.texi, cos.c:
	mpfr_round_prec is now obsolete
	new function mpfr_prec_round replaces it

2003-09-18  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* mpfr-impl.h: Fix for C implementations with 16-bit int.

2003-09-18  Patrick Pelissier  <Patrick.Pelissier@loria.fr>

	 Optimization of macros MPFR_IS_INF, MPFR_IS_NAN and MPFR_IS_FP

2003-09-18  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* set_ld.c:
	Removed a comment that should have been removed in revision 1.8.

2003-09-15  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* div.c:
	No longer perform the pre-check for exactness when first division step was
	actually a complete division. This introduced way too much overhead.

	* inp_str.c: replaced test stream==0 by stream==NULL

2003-09-15  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* round_prec.c, tests/tcan_round.c:
	Fixed a bug in mpfr_can_round_raw and added other mpfr_can_round
	tests.

	* round_prec.c, tests/tcan_round.c:
	Added a test to tests/tcan_round.c and assertions to round_prec.c.

2003-09-14  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* tests/texceptions.c, exceptions.c, exp.c:
	Fixed mpfr_set_overflow, added tests for mpfr_set_underflow
	and mpfr_set_overflow, and reverted exp.c.

2003-09-13  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* exp.c: overflow with round to zero was incorrect

2003-09-11  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* Makefile.am, clears.c, inits.c, inits2.c, mpfr.h, mpfr.texi, tests/Makefile.am, tests/tinits.c:
	New functions mpfr_inits, mpfr_inits2 and mpfr_clears to initialize or
	free several floating-point numbers (written by Patrick Plissier).

2003-09-09  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* TODO, zeta.c:
	Replaced malloc/free by __gmp_allocate_func/__gmp_free_func in
	mpfr_zeta_pos. zeta.c still uses math (libm) functions -> TODO:
	remove this dependence.

	* tests/tui_pow.c:
	Added a test that makes MPFR crash (coming from the mpfr_zeta crash).

	* tests/tzeta.c:
	Case that crashes MPFR (coming from test_generic) -> function test1.

	* ui_pow.c:
	Ended up by simplifying mpfr_ui_pow to fix it completely (with a
	call to mpfr_pow, in a way similar to other ui functions). There
	isn't significant differences with the old code anyway, and the
	case integer^integer wasn't optimized like in mpfr_pow.
	The test tui_pow now passes, but the test tzeta now fails!

	* tests/tui_pow.c, ui_pow.c:
	Code clean-up and reindented. Replaced a 8 by CHAR_BIT,
	as CHAR_BIT isn't necessarily equal to 8. The bug seems
	to occur on all machines.

2003-09-08  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* tests/tui_pow.c:
	Added a test to reproduce a bug (to be fixed later) on all 64-bit
	machines.

	* tests/tset_str.c: Added a cast (useful under Linux/alpha).

2003-09-01  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* mpfr.h, mpfr.texi, print_rnd_mode.c, TODO:
	Changes (Patrick Pelissier's suggestions):
	  _ mpfr_print_rnd_mode now has __gmp_const char * return type;
	  _ some corrections in mpfr.texi, documentencoding set.

2003-08-30  Kevin Ryde  <user42@zip.com.au>

	* tests/Makefile.am (EXTRA_libfrtests_a_SOURCES): Add amd64.asm.

	* tests/amd64.asm: New file.

	comments.

	* acinclude.m4 (MPFR_CONFIGS): Add amd64-*-* to x86 test objects.

	* tests/tset_ld.c (check_set_get): Improve error messages.

	* mpfr-test.h, tests/tests.c (ld_trace): New function.

	* set_ld.c (ldbl_max_struct): Use octal character constants, since hex
	is an ANSI-ism.

2003-08-07  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* ui_pow_ui.c: Avoid a potential overflow.

2003-08-04  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* agm.c, tests/tagm.c: fixed pb found by Damien Fisher

2003-07-24  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* get_d.c:
	If the exponent of the number is meaningless (src = NaN, inf or 0),
	0 is stored in expptr (behavior similar to the ISO C frexp function).

2003-07-21  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* TODO: added one item

2003-07-19  Kevin Ryde  <user42@zip.com.au>

	* tests/Makefile.am (check_PROGRAMS): Add tget_d_2exp.c.

	* tests/tget_d_2exp.c: New file, partly derived from tget_d.c.

	* get_d.c (mpfr_get_d_2exp): Ensure 0.5 <= abs(ret) < 1.0 is respected
	when rounding away from zero.

	* mpfr-test.h, tests/tests.c (d_trace): New function.

	* mpfr.texi (Converting Floats): mpfr_get_d_2exp stores to a long.

	* get_d.c (mpfr_get_d_2exp): Store exp in a long, same as
	mpz_get_d_2exp and mpf_get_d_2exp.

2003-07-18  Kevin Ryde  <user42@zip.com.au>

	* mpfr.h (mpfr_get_d_2exp): Store exp in a long, same as

	* mpfr.texi, round_prec.c: can_round returns 0 for NaN/Inf

	* round_prec.c: fixed Uninitialized memory read in mpfr_can_round
	(when b is NaN or Inf)

2003-06-30  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* tests/tget_str.c:
	fixed array bound write (need 6+1 characters in s1 to represent -@inf@ + \0)

2003-06-28  Kevin Ryde  <user42@zip.com.au>

	* get_d.c: Add "const" to IEEE byte sequence data.

	* tests/tests.c (tests_rand_end): Remove explicit __gmp_rands
	clearing, it's what RANDS_CLEAR does already.

2003-06-26  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* cmp_d.c, get_d.c, get_ld.c, mpfr-impl.h, set_d.c, set_dfl_prec.c, set_ld.c:

	* Makefile.am (libmpfr_a_SOURCES): Remove mpfr-math.h.

	* get_d.c (MPFR_DBL_INFP, MPFR_DBL_INFM, MPFR_DBL_NAN): Make private
	definitions based on IEEE byte sequences, in particular avoid HUGE_VAL
	from mpfr-math.h since that's not infinity on hppa1.1-hp-hpux10.
	Remove includes of mpfr-math.h, math.h and stddef.h.

	* tests/tget_d.c (check_inf_nan): New test.

	* acinclude.m4 (MPFR_C_LONG_DOUBLE_FORMAT): Use octal char constants,
	'\xHH' is an ANSI-ism.

2003-06-24  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* tests/tset_ld.c:
	check 2^1024 only when sizeof(long double) > sizeof(double)

	* tests/tsub.c: correction to previous patch

	* tests/tadd.c:
	correction to previous patch: problem was that x and u can be 0,
	then MPFR_PREC() undefined

2003-06-24  Kevin Ryde  <user42@zip.com.au>

	* tests/tests.c (tests_start_mpfr): Make stdout and stderr unbuffered.

	* tests/tsub.c, tests/tadd.c (check_inexact):
	For pz, use at least MPFR_PREC_MIN
	since this is required by mpfr_set_prec.

	changed since mpfr_random now can return 0

2003-06-20  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* random.c:
	The distribution should now be uniform (mpfr_random implemented
	by calling mpfr_urandomb).

	Take the current exponent range into account in mpfr_urandomb
	(which now returns an int).

2003-06-18  Kevin Ryde  <user42@zip.com.au>

	* tests/tset_z.c, tests/tset_si.c:
	Don't use mpz_get_d1, since a 53-bit double is not
	enough when long is 64-bits.

2003-06-13  Kevin Ryde  <user42@zip.com.au>

	* tests/tests.c: Use autoconf recommended style for time.h with

	Patch by Torbjorn: use puts not putchar, to avoid GNUPro compiler bug.

2003-06-08  Kevin Ryde  <user42@zip.com.au>

	* tests/tsqrt.c: Disable "8093416094703476*2^(-1075)" because mips64
	SGI cc doesn't seem to like the value (a denorm).

	* get_d.c: Include <stddef.h> before <math.h>, to avoid problems with
	gcc 3.2 on hppa2.0w-hp-hpux11.11.

	seemed to work, but perhaps not for rigorous reasons).

	* tests/tzeta.c: Added test for case s = 1.

	* round_prec.c (mpfr_round_prec):
	Bug fixed (case zero wasn't taken into account)

	Macros MPFR_EXP_INVALID (invalid exponent value) and MPFR_EXP_CHECK
	added. Code update to use MPFR_GET_EXP and MPFR_SET_EXP instead of
	MPFR_EXP to allow more bug detection related to special values.
	Macros MPFR_SET_NAN, MPFR_SET_INF, MPFR_SET_ZERO and MPFR_INIT set
	the exponent of the number to MPFR_EXP_INVALID if MPFR_EXP_CHECK
	is defined. Compile with -DMPFR_EXP_CHECK and make check to see

2003-01-07  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* exp2.c: fixed pb for underflow and rounding to nearest

	* mpfr-impl.h, set_ld.c: added macro LONGDOUBLE_ISNAN
	use LONGDOUBLE_ISNAN in set_ld instead of cast to double and DOUBLE_ISNAN
	(did raise exception under freebsd)

2003-01-07  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* exp2.c:
	Added assertions that can be resolved at compile time: the exponents
	must be representable in a long int (IMHO, this limitation should be
	avoided in a clean way).

2003-01-06  Kevin Ryde  <user42@zip.com.au>

	* TODO: Remove mpfr_get_ld, done.

	* TODO: Remove mpfr_set_machine_rnd_mode, done.

2003-01-06  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

2003-01-06  Kevin Ryde  <user42@zip.com.au>

	* set_str.c:
	Use separate function calls to second strncasecmp and strncmp
	for consistency and to avoid gcc warnings.

2003-01-06  Paul Zimmermann  <Paul.Zimmermann@loria.fr>

	* exp2.c, tests/texp2.c: fixed infinite loop for 2^integer

2003-01-03  Kevin Ryde  <user42@zip.com.au>

	* tests/tests.c, mpfr-test.h:
	(<sys/fpu.h>) [__mips]: Move from mpfr-test.h to tests/tests.c,
	and conditionalize with HAVE_SYS_FPU_H.

	* acinclude.m4 (AC_CHECK_HEADERS): Add sys/fpu.h.

	* mpfr-test.h:
	(HAVE_DENORMS) [__mips]: Remove this, let the configure test decide.

	* set_str.c:
	Use separate function calls to strncasecmp and strncmp, rather than
	?: on function pointers, since the latter demands declarations not
	present on SunOS.  Both forms are optimized the same by gcc.

2003-01-03  Vincent Lefevre  <Vincent.Lefevre@loria.fr>

	* BUGS:
	Added some potential bugs (mpfr_exp2 is known to have such a bug).
