Web6. Changing fixed point representations is commonly called 'scaling'. If you can do this with a class with no performance penalty, then that's the way to go. It depends heavily on the compiler and how it inlines. If there is a performance penalty using classes, then you need a more traditional C-style approach.

WebNov 23, 2024 · The term "Fixed-Point" refers to the position of the binary point. The binary point is analogous to the decimal point of a base-ten number, but since this is binary rather than decimal, a different term is used. In binary, bits can be either 0 or 1 and there is no separate symbol to designate where the binary point lies.
