"Web19 jul. 2024 · The bigger the input value, the less accurate this method is. Since cosine repeats every 2pi, we want to just do x = x % (2*pi);. However, in C the modulus operator doesn't work on floating point numbers, so we made our own. This is better for values over 2pi, but it is still very inaccurate leading up to 2pi.
