That only works for unsigned types.
it does work for bounded signed and unsigned integers, unbounded unsigned integers and also for floating point values (with denormalization)
Signed integer types use two's complement, so the absolute value of the largest positive and largest negative value differs.
so what? honestly i don't catch your point
-traits::max() != largest negative _____ Rob Stewart robert.stewart@sig.com Software Engineer, Core Software using std::disclaimer; Susquehanna International Group, LLP http://www.sig.com IMPORTANT: The information contained in this email and/or its attachments is confidential.
