there is one problem ... if you multiply the denormal number with the 1 or 0, you will probably have one denormal operation on the cpu instead of a branch ... i don't know, that's worse ... but definitely, some benchmarks would be useful for any denormal flushing algorithm... cheers... -- mailto:[EMAIL PROTECTED] ICQ: 96771783 After one look at this planet any visitor from outer space would say "I want to see the manager."
