// canonicalized number if one operand is a number and the other a quiet NaN. Otherwise it
// is either x or y, canonicalized (this means results might differ among implementations).
// When either x or y is a signalingNaN, then the result is according to 6.2.

// Since we do not support sNaN in Rust yet, we do not need to handle them.
// multiplying by 1.0. Should switch to the `canonicalize` when it works.
