I don't understand your "IEEE = IEEE". To make things clearer: IEEE 754 explicitly allows an extended exponent range. The ISO C language doesn't. But this can be solved by stores, then there wouldn't by any problem as far as the standards are concerned. -- Vincent Lefèvre <[EMAIL PROTECTED]> - Web: <http://www.vinc17.org/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.org/blog/> Work: CR INRIA - computer arithmetic / SPACES project at LORIA
