Last active September 15, 2022 00:31
A C++ implementation of fixed point math
#include "fixedp.h"
#include <iostream>
int main(int, char **)
{
fixedp<true, 16, 16> x(0); //32-bit signed 16.16 fixed-point number
fixedp<false, 8, 8> y(10); //16-bit unsigned 8.8 fixed-point number
std::cout << (fixedp<false, 4, 4>(3.5) + fixedp<false, 4, 4>(4.5)).toFloat() << std::endl;
//prints "8"
