WebSep 27, 2024 · Floating-point representations of real numbers have significant advantages over fixed-point. For example, given a fixed bit width for binary encoding, floating-point formats cover a much wider range of values without losing precision. However, FPUs are much harder to implement in hardware than integer or fixed-point arithmetic. WebFixed-point subtraction can be calculated in a similar manner to a 2's complement subtraction (addition with a negative). The difference being the "point" bookkeeping required which is the same as addition. For addition and subtraction the points need to be aligned before the operation (bookkeeping).
