I can't answer you directly, as this is the very stuff I'm still trying to learn. But here's at least something. Ada 83 was influenced by the "Brown model," documented in A Simple but Realistic Model of Floating-Point Computation W. S. Brown ACM Tranactions on Mathematical Software Vol. 7, No. 4, December 1981, p 445-480 Even today, after many years of Ada programming, I'm still not sure what a "safe" number is, though I think I understand what a model number is. -------------------------------------------------------------------- Matthew Heaney Software Development Consultant (818) 985-1271
