Citation? They are generally IEEE compliant; there can be some differences in denorm handling?
- mmarx 9y agoIEEE compliance only gives you guarantees on individual arithmetic operations. Vector machines take away control over the order in which operations are performed, but floating-point addition is not associative. Changing the order in which the terms of a sum are added may lead to vastly different results, due to, e.g., truncation.
