Huh? This is just false, isn't it? AFAIK, it pins down behavior, and the differences come from things like changing the order of operations (i.e. accumulating rounding error in a different order). I'm not an expert, though.
- gnabgib 6mo agoIt does not pin down the behaviour.. just a storage format. See the NaNs (many representations, unspecified bits), the zeros (both), subnormals, the multiple rounding rules (no behaviour required). https://en.wikipedia.org/wiki/IEEE_754 https://en.wikipedia.org/wiki/IEEE_754
