// ALGORITHM DESCRIPTION
//
// Below we suppose that there is log(z) function which takes an long
// double argument and returns result as a pair of long double numbers
// lnHi and lnLo (such that sum lnHi + lnLo provides ~80 correct bits
// of significand). Algorithm description for such log(z) function
// see below.
// Also, it this algorithm description we use the following notational
// conventions:
// a) pair A = (Ahi, Alo) means number A represented as sum of Ahi and Alo
// b) C = A + B = (Ahi, Alo) + (Bhi, Blo) means multi-precision addition.
//    The result would be C = (Chi, Clo). Notice, that Clo shouldn't be
//    equal to Alo + Blo
// c) D = A*B = (Ahi, Alo)*(Bhi, Blo) = (Dhi, Dlo) multi-precisiion
//    multiplication.
//
// So, lgammal has the following computational paths:
// 1) |x| < 0.5
//    P = A1*|x| + A2*|x|^2 + ... + A22*|x|^22
//    A1, A2, A3 represented as a sum of two double precision
//    numbers and multi-precision computations are used for 3 higher
//    terms of the polynomial. We get polynomial as a sum of two
//    double extended numbers: P = (Phi, Plo)
//    1.1) x > 0
//         lgammal(x) = P - log(|x|) = (Phi, Plo) - (lnHi(|x|), lnLo(|x|))
//    1.2) x < 0
//         lgammal(x) = -P - log(|x|) - log(sin(Pi*x)/(Pi*x))
//         P and log(|x|) are computed by the same way as in 1.1;
//         - log(sin(Pi*x)/(Pi*x)) is approximated by a polynomial Plnsin.
//         Plnsin:= fLnSin2*|x|^2 + fLnSin4*|x|^4 + ... + fLnSin36*|x|^36
//         The first coefficient of Plnsin is represented as sum of two
//         double precision numbers (fLnSin2, fLnSin2L). Multi-precision
//         computations for higher two terms of Plnsin are used.
//         So, the final result is reconstructed by the following formula
//         lgammal(x) = (-(Phi, Plo) - (lnHi(|x|), lnLo(|x|))) -
//                      - (PlnsinHi,PlnsinLo)
//
// 2)    0.5 <= x <   0.75  -> t = x - 0.625
//     -0.75 <  x <= -0.5   -> t = x + 0.625
//      2.25 <= x <   4.0   -> t = x/2 - 1.5
//       4.0 <= x <   8.0   -> t = x/4 - 1.5
//       -0.5 < x <= -0.40625 -> t = x + 0.5
//       -2.6005859375 < x <= -2.5 -> t = x + 2.5
//       1.3125 <= x < 1.5625 -> t = x - LOC_MIN, where LOC_MIN is point in
//                                   which lgammal has local minimum. Exact
//                                   value can be found in the table below,
//                                   approximate value is ~1.46
//
//    lgammal(x) is approximated by the polynomial of 25th degree: P25(t)
//    P25(t) = A0 + A1*t + ... + A25*t^25 = (Phi, Plo) + t^4*P21(t),
//    where
//    (Phi, Plo) is sum of four highest terms of the polynomial P25(t):
//    (Phi, Plo) = ((A0, A0L) + (A1, A1L)*t) + t^2 *((A2, A2L) + (A3, A3L)*t),
//    (Ai, AiL) - coefficients represented as pairs of DP numbers.
//
//    P21(t) = (PolC(t)*t^8 + PolD(t))*t^8 + PolE(t),
//    where
//    PolC(t) = C21*t^5 + C20*t^4 + ... + C16,
//    C21 = A25, C20 = A24, ..., C16 = A20
//
//    PolD(t) = D7*t^7 + D6*t^6 + ... + D0,
//    D7 = A19, D6 = A18, ..., D0 = A12
//
//    PolE(t) = E7*t^7 + E6*t^6 + ... + E0,
//    E7 = A11, E6 = A10, ..., E0 = A4
//
//    Cis and Dis are represented as double precision numbers,
//    Eis are represented as double extended numbers.
//
// 3) 0.75 <=  x < 1.3125   -> t = x - 1.0
//    1.5625 <= x < 2.25   -> t = x - 2.0
//    lgammal(x) is approximated by the polynomial of 25th degree: P25(t)
//    P25(t) = A1*t + ... + A25*t^25, and computations are carried out
//    by similar way as in the previous case
//
// 4) 10.0 < x <= Overflow Bound ("positive Sterling" range)
//    lgammal(x) is approximated using Sterling's formula:
//    lgammal(x) ~ ((x*(lnHi(x) - 1, lnLo(x))) - 0.5*(lnHi(x), lnLo(x))) +
//                 + ((Chi, Clo) + S(1/x))
//    where
//    C = (Chi, Clo) - pair of double precision numbers representing constant
//    0.5*ln(2*Pi);
//    S(1/x) = 1/x * (B2 + B4*(1/x)^2 + ... + B20*(1/x)^18), B2, ..., B20 are
//    Bernulli numbers. S is computed in native precision and then added to
//    Clo;
//    lnHi(x) - 1 is computed in native precision and the multiprecision
//    multiplication (x, 0) *(lnHi(x) - 1, lnLo(x)) is used.
//
// 5) -INF < x <= -2^63, any negative integer < 0
//    All numbers in this range are integers -> error handler is called
//
// 6) -2^63 < x <= -0.75 ("negative Sterling" range), x is "far" from root,
//    lgammal(-t) for positive t is approximated using the following formula:
//    lgammal(-t) = -lgammal(t)-log(t)-log(|dT|)+log(sin(Pi*|dT|)/(Pi*|dT|))
//        where dT = -t -round_to_nearest_integer(-t)
//    Last item is approximated by the same polynomial as described in 1.2.
//    We split the whole range into three subranges due to different ways of
//    approximation of the first terms.
//    6.1) -2^63 < x < -6.0 ("negative Sterling" range)
//       lgammal(t) is approximated exactly as in #4. The only difference that
//       for -13.0 < x < -6.0 subrange instead of Bernulli numbers we use their
//       minimax approximation on this range.
//       log(t), log(|dT|) are approximated by the log routine mentioned above.
//    6.2) -6.0 < x <= -0.75, |x + 1|> 2^(-7)
//       log(t), log(|dT|) are approximated by the log routine mentioned above,
//       lgammal(t) is approximated by polynomials of the 25th degree similar
//       to ones from #2. Arguments z of the polynomials are as follows
//       a) 0.75 <= t < 1.0 - 2^(-7),  z = 2*t - 1.5
//       b) 1.0 - 2^(-7)  < t < 2.0,   z = t - 1.5
//       c) 2.0  < t < 3.0,   z = t/2 - 1.5
//       d) 3.0  < t < 4.0,   z = t/2 - 1.5. Notice, that range reduction is
//          the same as in case c) but the set of coefficients is different
//       e) 4.0  < t < 6.0,   z = t/4 - 1.5
//    6.3) |x + 1| <= 2^(-7)
//       log(1 + (x-1)) is approximated by Taylor series,
//       log(sin(Pi*|dT|)/(Pi*|dT|)) is still approximated by polynomial but
//       it has just 4th degree.
//       log(|dT|) is approximated by the log routine mentioned above.
//       lgammal(-x) is approximated by polynomial of 8th degree from (-x + 1).
//
// 7) -20.0 < x < -2.0, x falls in root "neighbourhood".
//    "Neighbourhood" means that |lgammal(x)| < epsilon, where epsilon is
//    different for every root (and it is stored in the table), but typically
//    it is ~ 0.15. There are 35 roots significant from "double extended"
//    point of view. We split all the roots into two subsets: "left" and "right"
//    roots. Considering [-(N+1), -N] range we call root as "left" one if it
//    lies closer to -(N+1) and "right" otherwise. There is no "left" root in
//    the [-20, -19] range (it exists, but is insignificant for double extended
//    precision). To determine if x falls in root "neighbourhood" we store
//    significands of all the 35 roots as well as epsilon values (expressed
//    by the left and right bound).
//    In these ranges we approximate lgammal(x) by polynomial series of 19th
//    degree:
//    lgammal(x) = P19(t) = A0 + A1*t + ...+ A19*t^19, where t = x - EDP_Root,
//    EDP_Root is the exact value of the corresponding root rounded to double
//    extended precision. So, we have 35 different polynomials which make our
//    table rather big. We may hope that x falls in root "neighbourhood"
//    quite rarely -> ther might be no need in frequent use of different
//    polynomials.
//    A0, A1, A2, A3 are represented as pairs of double precision numbers,
//    A4, A5 are long doubles, and to decrease the size of the table we
//    keep the rest of coefficients in just double precision
//

// Algorithm for log(X) = (lnHi(X), lnLo(X))
//
//   ALGORITHM
//
//   Here we use a table lookup method. The basic idea is that in
//   order to compute logl(Arg) for an argument Arg in [1,2), we
//   construct a value G such that G*Arg is close to 1 and that
//   logl(1/G) is obtainable easily from a table of values calculated
//   beforehand. Thus
//
//      logl(Arg) = logl(1/G) + logl(G*Arg)
//                = logl(1/G) + logl(1 + (G*Arg - 1))
//
//   Because |G*Arg - 1| is small, the second term on the right hand
//   side can be approximated by a short polynomial. We elaborate
//   this method in four steps.
//
//   Step 0: Initialization
//
//   We need to calculate logl( X ). Obtain N, S_hi such that
//
//      X = 2^N * S_hi exactly
//
//   where S_hi in [1,2)
//
//   Step 1: Argument Reduction
//
//   Based on S_hi, obtain G_1, G_2, G_3 from a table and calculate
//
//      G := G_1 * G_2 * G_3
//      r := (G * S_hi - 1)
//
//   These G_j's have the property that the product is exactly
//   representable and that |r| < 2^(-12) as a result.
//
//   Step 2: Approximation
//
//
//   logl(1 + r) is approximated by a short polynomial poly(r).
//
//   Step 3: Reconstruction
//
//
//   Finally, logl( X ) is given by
//
//   logl( X )   =   logl( 2^N * S_hi )
//                 ~=~  N*logl(2) + logl(1/G) + logl(1 + r)
//                 ~=~  N*logl(2) + logl(1/G) + poly(r).
//
//   IMPLEMENTATION
//
//   Step 0. Initialization
//   ----------------------
//
//   Z := X
//   N := unbaised exponent of Z
//   S_hi := 2^(-N) * Z
//
//   Step 1. Argument Reduction
//   --------------------------
//
//   Let
//
//      Z = 2^N * S_hi = 2^N * 1.d_1 d_2 d_3 ... d_63
//
//   We obtain G_1, G_2, G_3 by the following steps.
//
//
//      Define          X_0 := 1.d_1 d_2 ... d_14. This is extracted
//                      from S_hi.
//
//      Define          A_1 := 1.d_1 d_2 d_3 d_4. This is X_0 truncated
//                      to lsb = 2^(-4).
//
//      Define          index_1 := [ d_1 d_2 d_3 d_4 ].
//
//      Fetch           Z_1 := (1/A_1) rounded UP in fixed point with
//      fixed point     lsb = 2^(-15).
//                      Z_1 looks like z_0.z_1 z_2 ... z_15
//                      Note that the fetching is done using index_1.
//                      A_1 is actually not needed in the implementation
//                      and is used here only to explain how is the value
//                      Z_1 defined.
//
//      Fetch           G_1 := (1/A_1) truncated to 21 sig. bits.
//      floating pt.    Again, fetching is done using index_1. A_1
//                      explains how G_1 is defined.
//
//      Calculate       X_1 := X_0 * Z_1 truncated to lsb = 2^(-14)
//                           = 1.0 0 0 0 d_5 ... d_14
//                      This is accomplished by integer multiplication.
//                      It is proved that X_1 indeed always begin
//                      with 1.0000 in fixed point.
//
//
//      Define          A_2 := 1.0 0 0 0 d_5 d_6 d_7 d_8. This is X_1
//                      truncated to lsb = 2^(-8). Similar to A_1,
//                      A_2 is not needed in actual implementation. It
//                      helps explain how some of the values are defined.
//
//      Define          index_2 := [ d_5 d_6 d_7 d_8 ].
//
//      Fetch           Z_2 := (1/A_2) rounded UP in fixed point with
//      fixed point     lsb = 2^(-15). Fetch done using index_2.
//                      Z_2 looks like z_0.z_1 z_2 ... z_15
//
//      Fetch           G_2 := (1/A_2) truncated to 21 sig. bits.
//      floating pt.
//
//      Calculate       X_2 := X_1 * Z_2 truncated to lsb = 2^(-14)
//                           = 1.0 0 0 0 0 0 0 0 d_9 d_10 ... d_14
//                      This is accomplished by integer multiplication.
//                      It is proved that X_2 indeed always begin
//                      with 1.00000000 in fixed point.
//
//
//      Define          A_3 := 1.0 0 0 0 0 0 0 0 d_9 d_10 d_11 d_12 d_13 1.
//                      This is 2^(-14) + X_2 truncated to lsb = 2^(-13).
//
//      Define          index_3 := [ d_9 d_10 d_11 d_12 d_13 ].
//
//      Fetch           G_3 := (1/A_3) truncated to 21 sig. bits.
//      floating pt.    Fetch is done using index_3.
//
//      Compute         G := G_1 * G_2 * G_3.
//
//      This is done exactly since each of G_j only has 21 sig. bits.
//
//      Compute
//
//               r := (G*S_hi - 1)
//
//
//  Step 2. Approximation
//  ---------------------
//
//   This step computes an approximation to logl( 1 + r ) where r is the
//   reduced argument just obtained. It is proved that |r| <= 1.9*2^(-13);
//   thus logl(1+r) can be approximated by a short polynomial:
//
//      logl(1+r) ~=~ poly = r + Q1 r^2 + ... + Q4 r^5
//
//
//  Step 3. Reconstruction
//  ----------------------
//
//   This step computes the desired result of logl(X):
//
//      logl(X)  =   logl( 2^N * S_hi )
//               =   N*logl(2) + logl( S_hi )
//               =   N*logl(2) + logl(1/G) +
//                      logl(1 + G*S_hi - 1 )
//
//   logl(2), logl(1/G_j) are stored as pairs of (single,double) numbers:
//   log2_hi, log2_lo, log1byGj_hi, log1byGj_lo. The high parts are
//   single-precision numbers and the low parts are double precision
//   numbers. These have the property that
//
//      N*log2_hi + SUM ( log1byGj_hi )
//
//   is computable exactly in double-extended precision (64 sig. bits).
//   Finally
//
//      lnHi(X) := N*log2_hi + SUM ( log1byGj_hi )
//      lnLo(X) := poly_hi + [ poly_lo +
//              ( SUM ( log1byGj_lo ) + N*log2_lo ) ]
