Currently "functional/hash - hash_float_test" fails on Tru64/CXX6.5 (See http://tinyurl.com/8opfo)
The reason of the failure is that QNaN and 0 give the same hash code on this platform. I was wondering what the expected hash of QNAN actually should be. Is it some platform dependent value?
Am I missing something here? Since it is obvious that one canNOT generate a unique hash for all possible inputs, why should there necessarily be a difference between any 2?
You're probably right. Maybe the author of the test could perhaps clarify the motivation for this test, then. Markus
