WebMar 31, 2024 · For a given fixed-point type, there is a fixed scale which is a power of two (or ten). To convert from the real value to the integer representation, multiply by that scale. To convert back again, simply divide. Then the issue of how negative values are represented becomes a detail of the integer type with which you are representing your …

WebIf you need to use fixed-point, then you must implement addition and multiplication operations. In that case, you need to worry about how many bits you have allocated for the fractional part and how many bits allocated for the integer part. And then you can do "shift" operation as your preference. WebFeb 10, 2024 · When constructing a fixed-point number, the opposite occurs and you “shift” the value so that you can store it as an integer (with the floating point number 1.23 you would divide by 0.01 if you were using scale -2.
