WebAug 2, 2024 · Floating-point decimal values generally do not have an exact binary representation. This is a side effect of how the CPU represents floating point data. For this reason, you may experience some loss of precision, and some floating-point operations may produce unexpected results. This behavior is the result of one of the following: 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.
