7.12.8.4 The tgamma functions

Synopsis

1

#include <math.h>
double tgamma(double x);
float tgammaf(float x);
long double tgammal(long double x);

Description

2

The tgamma functions compute the gamma function of x. A domain error or range error may occur if x is a negative integer or zero. A range error may occur if the magnitude of x is too large or too small.

Returns

3

The tgamma functions return (Gamma)(x).
