This is pretty much complete with the exception of lrint not yet implemented. One thing I've noted running the unittests are that while the functions produce accurate results, this is only true up to 64bit precision. The remaining 16bits bits going slightly off target. eg: exp(1.0L) == E; // true exp(3.0L) == E*E*E; // false -- Iain Buclaw *(p < e ? p++ : p) = (c & 0x0f) + '0'; _______________________________________________ dmd-internals mailing list [email protected] http://lists.puremagic.com/mailman/listinfo/dmd-internals
