Internally, singles are stored as 4-byte (32-bit) IEEE values. Thus, when appearing within a structure, singles require 4 bytes of storage. When used with binary or random files, 4 bytes of storage is required.
Each single consists of the following
- A 1-bit sign
- An 8-bit exponent
- A 24-bit mantissa
