Also, variables are only used without the $ sign on the left side of the = sign and there should be no space before or after the = sign.

NAME
lgamma, lgammaf, lgamma_r, lgammaf_r, gamma, gammaf, gamma_r, gammaf_r, tgamma, tgammaf -- log gamma function LIBRARY
Math Library (libm, -lm) SYNOPSIS
#include <math.h> extern int signgam; double lgamma(double x); float lgammaf(float x); double lgamma_r(double x, int *sign); float lgammaf_r(float x, int *sign); double gamma(double x); float gammaf(float x); double gamma_r(double x, int *sign); float gammaf_r(float x, int *sign); double tgamma(double x); float tgammaf(float x); DESCRIPTION
_ lgamma(x) returns ln|| (x)|. _ The external integer signgam returns the sign of | (x). _ lgamma_r() is a reentrant interface that performs identically to lgamma(), differing in that the sign of | (x) is stored in the location pointed to by the sign argument and signgam is not modified. _ The tgamma(x) and tgammaf(x) functions return | (x), with no effect on signgam. gamma(), gammaf(), gamma_r(), and gammaf_r() are deprecated aliases for lgamma(), lgammaf(), lgamma_r(), and lgammaf_r(), respectively. IDIOSYNCRASIES
_ Do not use the expression ``signgam*exp(lgamma(x))'' to compute g := | (x). Instead use a program like this (in C): lg = lgamma(x); g = signgam*exp(lg); Only after lgamma() has returned can signgam be correct. RETURN VALUES
lgamma() returns appropriate values unless an argument is out of range. Overflow will occur for sufficiently large positive values, and non- positive integers. For large non-integer negative values, tgamma() will underflow. On the VAX, the reserved operator is returned, and errno is set to ERANGE. SEE ALSO
math(3) HISTORY
The lgamma function appeared in 4.3BSD. The tgamma() function appeared in NetBSD 6.0. BSD
