Description

The standard defines the floating-point data type float (32-bits or 4-bytes). The encoding used is the IEEE standard for normalized single-precision floating-point numbers [1]. The following three fields describe the single-precision floating-point number:

S: The sign of the number. Values 0 and 1 represent positive and negative, respectively. One bit.

E: The exponent of the number, base 2. There are eight bits in this field. The exponent is biased by 127.

F: The fractional part of the number's mantissa, base 2. There are 23 bits are in this field.

Therefore, the floating-point number is described by:

(-1)**S * 2**(E-Bias) * 1.F
