Really, how much more accurate is SANE? It >certainly isn't worth the slowdown it produces, not to me it isn't. Using the 68882 instead of SANE loses 12 bits of precision. The 68882 only computes trancendentals to the accuracy of double precision rather than extended precision. (square root excepted) Ray Fischer rcfische@polyslo.calpoly.edu
