Floating point binary multiplication
WebDec 4, 2024 · Binary floating point formats (such as IEEE754 binary64 aka double) can cheaply multiply or divide by powers of 2 just by adding or subtracting from the exponent field! (You have to check for overflow, though). Hardware doesn't always provide this as a separate operation, so often you do just multiply by 0.5 with the regular instruction. WebArithmetic operations on floating point numbers consist of addition, subtraction, multiplication and division. The operations are done with algorithms similar to those used on sign magnitude integers (because of …

I expect that a fully functional multiplication routine to take 3 times as much code as you've shown – Nayuki Mar 2, 2024 at 2:17 Add a comment 2 Answers Sorted by: 2
The fact that floating-point numbers cannot precisely represent all real numbers, and that floating-point operations cannot precisely represent true arithmetic operations, leads to many surprising situations. This is related to the finite precision with which computers generally represent numbers. For example, the non-representability of 0.1 and 0.01 (in binary) means that the result of attempting to square 0.1 is neither 0.01 nor the representable number closest to it.
