+ *+ * This routine calculates the LOG(GAMMA) function for a positive real argument X. + * Computation is based on an algorithm outlined in references 1 and 2. + * The program uses rational functions that theoretically approximate LOG(GAMMA) + * to at least 18 significant decimal digits. The approximation for X > 12 is from + * reference 3, while approximations for X < 12.0 are similar to those in reference + * 1, but are unpublished. The accuracy achieved depends on the arithmetic system, + * the compiler, the intrinsic functions, and proper selection of the + * machine-dependent constants. + *
+ *
+ * Error returns:
+ * The program returns the value XINF for X .LE. 0.0 or when overflow would occur.
+ * The computation is believed to be free of underflow and overflow.
