- dpsi
- Compute the derivatives of the psi function and polygamma functions.
- euclidean

- fixup
- gamma
- This function computes the value of the gamma function. The accuracy of this routine compares (very) favourably with those of the Sun Microsystems portable mathematical library.
- gamma_
cody - This routine calculates the GAMMA function for a float argument X. Computation is based on an algorithm outlined in reference [1]. The program uses rational functions that approximate the GAMMA function to at least 20 significant decimal digits. Coefficients for the approximation over the interval (1,2) are unpublished. Those for the approximation for X >= 12 are from reference [2]. The accuracy achieved depends on the arithmetic system, the compiler, the intrinsic functions, and proper selection of the machine-dependent constants.
