2011-05-20 Brian Gough <bjg@network-theory.co.uk>

2009-08-21 Brian Gough <bjg@network-theory.co.uk>
* test.c (main): move x/=2 outside test of while loops because it
is (possibly) not volatile.
2008-10-13 Brian Gough <bjg@network-theory.co.uk>
* log1p.c: use gsl_sys.h header file

2007-11-04 Brian Gough <bjg@network-theory.co.uk>
* ldfrexp.c (gsl_ldexp): handle full range of double precision
(gsl_frexp): handle full range of double precision
2007-07-30 Brian Gough <bjg@network-theory.co.uk>
* infnan.c (gsl_finite): use isfinite (c99) in preference to
finite
2007-07-23 Brian Gough <bjg@network-theory.co.uk>
* log1p.c (gsl_log1p): added another volatile to prevent unwanted
optimisation
2007-04-03 Brian Gough <bjg@r51e.network-theory.co.uk>
* infnan.c (gsl_isinf): now return -1 for -Inf instead of +1
* test.c (main): add test for -inf
* infnan.c (gsl_finite): always use finite where available
(gsl_isnan): always use isnan where available
(gsl_isinf): always use isinf where available
2005-11-14 Brian Gough <bjg@network-theory.co.uk>
* test.c: added tests for constants
2005-04-05 Brian Gough <bjg@network-theory.co.uk>
* infnan.c: added #include ieeefp.h for Solaris
2004-12-22 Brian Gough <bjg@network-theory.co.uk>
* infnan.c (gsl_isinf): added missing return type of int
2003-09-02 Brian Gough <bjg@network-theory.co.uk>
* infnan.c (gsl_isinf): added fallback for missing isinf (IRIX)
2003-07-24 Brian Gough <bjg@network-theory.co.uk>
* invhyp.c: removed duplicate declarations
* ldfrexp.c: removed duplicate declarations
* expm1.c: removed duplicate declaration of gsl_expm1
2003-01-02 Brian Gough <brian.gough@network-theory.co.uk>
* infnan.c (gsl_isnan): fall back to isnan,isinf,finite/isfinite
if available and IEEE comparisons do not work
Wed Dec 11 17:29:24 2002 Brian Gough <brian.gough@network-theory.co.uk>
* ldfrexp.c: fix include to use <gsl/gsl_math.h> instead of
<gsl_math.h>
2002-08-25 Brian Gough <bjg@network-theory.co.uk>
* fcmp.c (gsl_fcmp): approximate comparison of floating point
numbers using Knuth's algorithm
* ldfrexp.c (gsl_ldexp): portable replacement for ldexp()
(gsl_frexp): portable replacement for frexp()
Wed Jan 16 16:35:58 2002 Brian Gough <bjg@network-theory.co.uk>
* test.c (main): only test gsl_isnan, gsl_isinf, gsl_finite
functions if they have been compiled in.
* infnan.c (gsl_isnan): #ifdef out the gsl_isnan, gsl_isinf and
gsl_finite functions if IEEE comparisons for nans and infs are not
supported (HAVE_IEEE_COMPARISONS).
Tue Aug 21 22:54:08 2001 Brian Gough <bjg@network-theory.co.uk>
* test.c (main): use inf/inf to generate a nan, because MSVC
optimizes inf-inf to zero
Sun May 6 14:28:57 2001 Brian Gough <bjg@network-theory.co.uk>
* infnan.c: added gsl_isnan, gsl_isinf, gsl_isreal
Sun Feb 25 11:54:21 2001 Brian Gough <bjg@network-theory.co.uk>
* invhyp.c: added gsl_acosh, gsl_asinh, gsl_atanh
Mon Jan 29 10:53:06 2001 Brian Gough <bjg@network-theory.co.uk>
* hypot.c: removed the inline from gsl_hypot, since this is the
static version of the function
* test.c (main): added an underflow test for gsl_hypot
Thu Nov 16 19:28:38 2000 Brian Gough <bjg@network-theory.co.uk>
* coerce.c: added functions for coercing values out of registers
so they are correctly rounded
Sun Oct 22 15:00:24 2000 Brian Gough <bjg@network-theory.co.uk>
* expm1.c (gsl_expm1): added gsl_expm1, a substitute for BSD's expm1
Mon Apr 3 16:58:53 2000 Brian Gough <bjg@network-theory.co.uk>

Tue Mar 21 12:44:07 2000 Brian Gough <bjg@network-theory.co.uk>
* hypot.c: added a quick gsl_hypot function for sqrt(x^2+y^2)
1999-07-14 Mark Galassi <rosalia@cygnus.com>
* prec.c (GSL_MODE_PREC): surrounded this with function with an
#ifndef, since it might already be defined as a macro. In truth,
this function might be completely unnecessary, since the logic in
../gsl_mode.h seems to cover all cases.
Fri Nov 20 17:41:35 1998 Brian Gough <bjg@vvv.lanl.gov>
* params.c: added program for printing ieee parameters
