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 … WebDec 2, 2016 · Fractions can be stored in single or double precision format, so the bits used for their representation can vary: Single (float) precision: needs 32 bits -> 1 bit for the sign, 8 for the exponent and 23 for the fraction part. Double: needs 64 bits -> 1 bit for the sign, 11 for the exponent and 52 for the fraction part. Share Cite
