[AMBER] Posits preparing to pounce on Floating Point

    Another important advantage to the format is that unlike
    conventional floats, posits produce the same bit-wise results on any
    system, which is something that cannot be guaranteed with the IEEE
    standard (even the same computation on the same system can product
    different results for floats). It also does away with rounding
    errors, overflow and underflow exceptions, subnormal (denormalized)
    numbers, and the plethora of not-a-number (NaN) values.
    Additionally, posits avoids the weirdness of 0 and -0 as two
    distinct values. Instead it uses an integer-like twos complement
    form to encapsulate the sign, which means that simple bit-wise
    comparisons are valid.
