Expand description

Compares each of the four floats in `a` to the corresponding element in `b`. Returns four floats that have one of two possible bit patterns. The element in the output vector will be `0xffffffff` if the input elements in `a` and `b` are unordered (i.e., at least on of them is a NaN), or 0 otherwise.
