WebJun 27, 2024 · As I understand it, to multiply two 16.16 fixed point numbers, you would ignore the decimal point and treat them as regular 32-bit integers, and multiply them with MULS.L. This produces a 64-bit result. Then you would right-shift the result 16 places, and take the bottom 32 of the 48 remaining bits, to get the result in 16.16 format. WebFixed-point and floating-point representations of numbers A xed-point representation of a number may be thought to consist of 3 parts: the sign eld, integer eld, and fractional eld.
