    A floating type represenation using an encoding scheme similiar to scientific notation. The first byte represents the exponent and the remaining represent the prexponential, with one bite reserved for the sign.

    The following table gives the range of values for floating systems in 32 and 64 bit binary encoding.

    Format Total bits Significand bits Exponent bits Smallest Number Largest Number
    Single precision 32 23 + sign 8 ca. 1.2 x10-38 ca. 3.4 x1038
    double precision 64 52 + sign 11 ca. 2.2 x10-308 ca. 1.8 x10308
