>Description:
The function gamma in the math library gives the wrong answer - it gives the
same answer as lgamma. For example gamma(6) should be 120. The following
C program gives 4.78749 which is log(120).
>How-To-Repeat:
#include <stdio.h>
#include <math.h>
main() {
double x=6;
printf("%g %g %g %g\n",x,gamma(x),lgamma(x),exp(lgamma(x)));
}
