OK, I didn't know that they were normalized. I had a quick look at http://www.validlab.com/754R/standards/754.ps (link from <http://www.validlab.com/754R/>), but I didn't see anything concerning transcendental functions. Perhaps an addition of IEC 60559 over IEEE 754? BTW, note that pow(�1, �inf) returns a NaN, so pow(1, nan) = 1 pow(1, inf) = 1 pow(1, -inf) = 1 are incorrect too. Some choices are a bit strange, e.g. pow(x, +inf) for -1 < x < 0. The standard says +0, but I think that -0 would have been more logical in the rounding to minus infinity. -- Vincent Lef�vre <[EMAIL PROTECTED]> - Web: <http://www.vinc17.org/> - 100% validated (X)HTML - Acorn Risc PC, Yellow Pig 17, Championnat International des Jeux Math�matiques et Logiques, TETRHEX, etc. Work: CR INRIA - computer arithmetic / SPACES project at LORIA -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
