## NAMEgamma, gammaf, gammal - (logarithm of the) gamma function ## SYNOPSIS#include <math.h> double gamma(double ## DESCRIPTIONThese functions are deprecated: instead, use either the tgamma(3) or the lgamma(3) functions, as appropriate. For the definition of the Gamma function, see tgamma(3). *BSD version The libm in 4.4BSD and some versions of FreeBSD had a gamma() function that computes the Gamma function, as one would expect. glibc version Glibc has a gamma() function that is equivalent to lgamma(3) and computes the natural logarithm of the Gamma function. ## RETURN VALUESee lgamma(3). ## ERRORSSee lgamma(3). ## CONFORMING TOBecause of historical variations in behavior across systems, this function is not specified in any standard. ## NOTESHistory 4.2BSD had a gamma() that computed ln(|Gamma(| ## SEE ALSOlgamma(3), signgam(3), tgamma(3) ## COLOPHONThis page is part of release 3.65 of the Linux |
