I am working on a number crunching program which makes numerous calls to expm1(). I checked its implementation in msun, I was surprised that it's not implemented with the f2xm1 i387 instruction, yet exp() is. I wonder if there is any reason why the C implementation is preferred over the FPU instruction? -lq To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
