| // Algorithm description |
| // --------------------- |
| // |
| // There are 3 main paths in the implementation |
| // (and additional special values branches) |
| // |
| // 1) |X| >= 13 - Stirling formula computation |
| // a) Positive arguments: |
| // TGAMMAL(X) = exp((X-0.5)*ln(X) - X + C + S(Z)), |
| // where C = 0.5*ln(2*Pi) , Z = 1/Z, S(Z) - Bernulli polynomial |
| // (up to 'B18' term). |
| // Some of these calculation done in multiprecision. |
| // Ln returns multiprecision result too |
| // and exp also accepts and returns pair of values. |
| // |
| // b) Negative arguments |
| // TGAMMAL(-X) = PI/(X*TGAMMAL(X)*sin(PI*X)). |
| // (X*sin(PI*X))/PI calculated in parallel with TGAMMAL. |
| // Here we use polynomial of 9th degree with 2 multiprecision steps. |
| // Argument range reduction is: |
| // N = [x] with round to nearest, r = x - N, -0.5 <= r < 0.5 |
| // After ((X-0.5)*ln(X) - X + C + S(Z)) completed we just invert |
| // its result and compute exp with negative argument (1/exp(x)=exp(-x)) |
| // Then we multiply exp result to PI/(X*sin(PI*X)). |
| // |
| // 2) 1 <= |X| < 13 - Polynomial part |
| // a) Positive arguments: |
| // All values are splitted to such intervals as: |
| // #0->[2;3], #1->[3,4], #2->[5,6]... |
| // For even intervals we just use polynomial computation with degree 20 |
| // and first 6 multiprecision computations. |
| // Range reduction looks like |
| // N = [x] with truncate, r = x - N - 0.5, -0.5 <= r < 0.5 |
| // For odd intervals we use reccurent formula: |
| // TGAMMAL(X) = TGAMMA(X-1)*(X-1) |
| // [1;2] interval is splitted to 3 subranges: |
| // [1;1.25], [1.25;1.75], [1.75;2] with the same polynomial forms |
| // |
| // b) Negative arguments |
| // TGAMMAL(-X) = PI/(X*TGAMMAL(X)*sin(PI*X)). |
| // (X*sin(PI*X))/PI calculated in parallel with TGAMMAL. |
| // After multiplication by TGAMMAL(X) result we calculate reciprocal |
| // and get final result. |
| // |
| // 3) 0 < |X| < 1 - Near 0 part |
| // a) Here we use reccurent formula TGAMMAL(X) = TGAMMAL(X+1)/X |
| // TGAMMAL(X+1) calculated as shown above, |
| // 1/X result obtained in parallel. Then we just multiply these values. |
| // There is only additional separated subrange: [0;0.125] with specific |
| // polynomial constants set. |
| // |
| // b) Negative arguments |
| // TGAMMAL(-X) = PI/(TGAMMAL(X+1)*sin(PI*X)). |
| // There is no need to compute 1/X. |
