1// Wasm's `min` and `max` operators implement the IEEE 754-2019
2// `minimum` and `maximum` operations, meaning that given a choice
3// between NaN and a number, they return NaN. This differs from
4// the C standard library's `fmin` and `fmax` functions, which
5// return the number. However, we can still use wasm's builtins
6// by handling the NaN cases explicitly, and it still turns out
7// to be faster than doing the whole operation in
8// target-independent C. And, it's smaller.
