Hmmm, something weird is going on at my end. I just wrote a standalone C program to test just these cases and some of them now work as expected! I do agree that -1.0 to either +-infinity should be a nan, but then using that same logic why is -1.1 to infinity and 0.9 to minus infinity equal to infinity and not nan? Personally I don't really care which way it's done. I just would like things to be consistent. One of the newlib pow implementations has some comments about how the special cases are handled, but the comments don't match the behavior I'm getting with either of my programs. I guess I need to track down exactly which pow is being called by each program. Based on what things look like now I'm betting some one redefined pow in the original program, grrr. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
