WebFixed-point computation is precisely the place where using a properly engineered class will save you from lots of bugs. Therefore, you should write a FixedPoint8 class. Test and debug it thoroughly. If you have to convince yourself of its performance as compared to using plain integers, measure it. WebSep 7, 2024 · Fixed point and floating point are two ways of representing numbers. In fixed point, there is a specific number of digits to represent the integer section and fraction section. In other words, there is a fixed number of digits for each portion even though the number is very large or small.
