Autzoo.1280 net.bugs.4bsd utzoo!henry Fri Jan 15 15:43:37 1982 gamma(3m) manual page The sample program given in the manual page for the gamma function is wrong, partly because the manual page is ambiguous. The value of signgam is not ==0 or !=0, it is >0 or <0. So the if in the program should read "if (signgam < 0)" not "if (signgam)".
