Half-precision floating-point format - Wikipedia

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 … WebFor example, float32 has 1 bit for the sign, 8 bits for the exponent, and 23 bits for the mantissa. For further reading on potential considerations with floating point numbers, see the Python documentation You can inspect the bits used in a floating point number in python using the bitstring package

WebNov 22, 2024 · A float has 23 bits of mantissa, and 2^23 is 8,388,608. 23 bits let you store all 6 digit numbers or lower, and most of the 7 digit numbers. This means that floating point numbers have between 6 and 7 digits of precision, regardless of exponent. That means that from 0 to 1, you have quite a few decimal places to work with.
