    I might be saying something stupid, but, I was under the impression
    that floating point '==', assuming it follows IEEE rules, does exactly
    this.

    I know for certain that it does not do memcmp(), as it has to deal
    with the exponent and mantissa being each off by +/-1 and <</>>1
    respectively.
