Hello,

I've tried this program under cygwin:

#include <math.h>

int main()
{
  printf("%lf\n", pow(2,8));
  return 0;
}

This program returns 8 instead of 256.
I've tried pow(2.0,8), pow(2.0, 8.0), etc ... Seems to me that I've found
a bug ?

instead of pow, I'm using pow(A,B)=exp(B*log(A)) (it works)

Your sincerely,

Yann COLLETTE

PS: What about a bugzilla page ?
