WebMay 13, 2024 · Using fixed-point formats does require converting input to the fixed-point format and converting numbers in the fixed-point format to output. But this is also true of integers and floating-point: All input must be converted to whatever internal format is used to represent it, and all output must be produced by converting from internal formats. WebAug 4, 2010 · Converting from a floating-point value to a fixed-point value involves the following steps: Multiply the float by 2^ (number of fractional bits for the type), eg. 2^8 for 24.8. Round the result (just add 0.5) if necessary, and floor it (or cast to an integer type) leaving an integer value. Assign this value into the fixed-point type.
