* - While SPARC V9 allows tininess to be detected either before or aftermarius2010-03-201-5/+10
| | | | | | | | | | | | | rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and UltraSPARC processors defines that in all cases tinyness is detected before rounding, therefore rounding up to the smallest normalised number should set the underflow flag. - If an infinite result is rounded down, the result should have an exponent 1 less than the value for infinity.
