        Floats are signed numbers that may include an
        integer part, a fractional part, and an order of magnitude (a
        power of ten by which the integer and fractional parts are
        multiplied.)   Freebase uses the 64-bit IEEE-754 <b>floating point</b>
        representation which supports magnitudes between
        10<sup>-324</sup> and 10<sup>308</sup>.
