Is it allowed to evaluate constant floating point expressions with greater range and precision than that of the execution environment in contexts where a constant is not required? There are unexpected implications of both allowing and disallowing such folding, but I cannot find a statement in the standard that unambiguously says what a translator may or may not do. -- Hans van Eck, Dept. of Mathematics and Computer Science, Vrije Universiteit, De Boelelaan 1081, 1081 HV Amsterdam, The Netherlands Voice: +31 20 5485302 Email: eck@cs.vu.nl
