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))); } >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
