Can the code below be modified such that it works correctly even when compiled by GCC with fast-math enabled?
#include <iostream>#include <float.h>using namespace std;int main(){ char divider = 2; float power = 1; float number = 1; float current = number + power; cout.precision(20); // Divide until rounded off while(current != number) { power /= divider; current = number + power; //cout << current << endl; } cout << power * divider << endl; cout << FLT_EPSILON << endl;}Note: I have it in a header file and I haven't managed to turn off fast math for the header.
