A simple header-only library for C++ to do fraction math.
NOTE: Fractions are not reduced/minimized on arithmetic-operations, but are reduced on comparisons.
Usage:
Copy fractions.h into your project.
auto f1 = Fraction<int32_t, int32_t>{-3, 9};
printf("f1: %s\n", f1.to_string().c_str());
f1.reduce();
printf("f1-reduced: %s\n", f1.to_string().c_str());
auto f2 = frac32::from_float(0.5248f);
printf("f2: %s\n", f2.to_string().c_str());Output:
f1: -3/9
f1-reduced: -1/3
f2: 328/625
f3: 6/21
