gamma(3m) gamma(3m)[top]Namegamma, lgamma, signgam - loggammafunctionSyntax#include <math.h> double gamma(x) double x; double lgamma(x) double x; extern intDescriptionThe function returns ln |Γ(|x|)|. The sign of Γ(|x|) is returned in the external integer The following C program might be used to calculate Γ: y = gamma(x); if (y > 88.0) error(); y = exp(y); if(signgam) y = -y; The function is another name for thegammafunction.Return ValuesThe and functions return HUGE_VAL and set errno to EDOM when x is an integer value less than or equal to zero. When the correct value would overflow they return HUGE_VAL and set errno to ERANGE.EnvironmentWhen your program is compiled using the System V environment for non‐ positive integer values, HUGE is returned, and errno is set to EDOM. A message indicating DOMAIN error is printed on the standard error out‐ put. If the correct value would overflow, returns HUGE and sets errno to ERANGE. These error-handling procedures may be changed with the functionSee Alsomatherr(3m) VAX gamma(3m)
