        // compared are both 0.0s (of either sign), the value in the second
        // operand (source operand) is returned. If a value in the second
        // operand is an SNaN, then SNaN is forwarded unchanged to the
        // destination (that is, a QNaN version of the SNaN is not returned). If
        // only one value is a NaN (SNaN or QNaN) for this instruction, the
        // second operand (source operand), either a NaN or a valid
        // floating-point value, is written to the result. If instead of this
        // behavior, it is required that the NaN source operand (from either the
        // first or second operand) be returned, the action of MAXPS can be
        // emulated using a sequence of instructions, such as, a comparison
        // followed by AND, ANDN, and OR."
