This doesn't remove from FPU makers the responsibility to make chips satisfying reasonably simple rules. You really can get a lot better performance out of numerical algorithms when, e.g., you're working under Knuth's model of floating-point computation. ANSI floating-point is an excellent start, and it's worth the effort for strict compliance. Anyway, this discussion belongs in sci.math or alt.chips.poor-engrg. Followups to the former. ---Dan
