If you go look in the source comments I believe it says which paper's algorithm it is using... doing range reduction for sin(6e5) is expensive to do accurately. Which is why the x86 sin() hardware instruction does it inaccurately but quickly, and most people/codes don't care. -- greg _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
