1.6.1. Floating-Point Formats

Single-precision floating-point format (sometimes called FP32 or float32) is a computer number format, usually occupying 32 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. A floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 … WebOct 31, 2024 · In binary, the only nonzero digit is 1, so it is not stored explicitly in the IEEE-754 representation of normal numbers.
