gamma(3m)							     gamma(3m)

Name
       gamma, lgamma, signgam - log gamma function

Syntax
       #include <math.h>

       double gamma(x)
       double x;

       double lgamma(x)
       double x;

       extern int

Description
       The  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 the gamma function.

Return Values
       The  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.

Environment
       When  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 function
