如何在 C# 中计算 fmod？

Question

For given floating point numbers x and a , I would like to compute r (and n ) such that x = a*n + r . In C/C++ this function is called fmod . However I do not see a convenient function in .NET. Math.DivRem is only for integers ...

Answer 1

I think you can just use % for floats as well. r = x % a

" Arithmetic operators (C# reference) ":

All numeric types have predefined modulus operators.
