How to compute fmod in C#?

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

All numeric types have predefined modulus operators.

Answer 2

I think you are looking for System.Math.IeeeRemainder
