WebMay 19, 2024 · Accuracy of a floating-point type is not related to PI or any specific numbers. It only depends on how many digits are stored in memory for that specific type. In case of IEEE-754 float uses 23 bits of mantissa so it can be accurate to 23+1 bits of precision, or ~7 digits of precision in decimal. WebDouble Precision vs. Single Precision In addition to the single precision floating point described here, there are also double precision floating point units. These have 64 bits instead of 32, and instead of field lengths of 1, 8, and 23 as in single precision, have field lengths of 1, 11, and 52. northern exposure similar tv showsWebFloating-point arithmetic operations are performed by software, and double precision is not supported at all.
