Float Binary (p <= 23) is a single-precision, basic format, binary floating-point number (ASCII/IEEE 754-1985 compliant). It contains a 1-bit sign, 8-bit biased exponent (bias = 127), and 23+(1)-bit binary fraction (hidden bit).
An exponent of 255 represents +/- infinity or not-a-number. +/- infinity is represented by an exponent of 255 and zero as the fraction part; the sign bit denotes the + or - infinity. Not-a-number is represented by an exponent of 255 and any non-zero value in the fraction part; the sign bit of not-a-number is not significant. An exponent of 0 denotes a denormalized small value of reduced precision. Both +0 and -0 are possible. Note that the range is approximate and indicates representable values, which include zero and both negative and positive numbers.
