3 | | //! |
4 | | //! Per the spec, returns: |
5 | | //! - `x` if `x < y` |
6 | | //! - `y` if `y < x` |
7 | | //! - Non-NaN if one operand is NaN |
8 | | //! - Logic following +0.0 > -0.0 |
9 | | //! - Either `x` or `y` if `x == y` and the signs are the same |
10 | | //! - qNaN if either operand is a NaN |
11 | | //! |
12 | | //! Excluded from our implementation is sNaN handling. |
