C# modulo operator [duplicate]

Question

Just recently I stumbled upon a problem using the (what I assumed to be modulo) operator %:

Basically (-1) % 5 returns -1 instead of 4, so % seems to return the remainder instead of the mathematically correct modulus (either that or Wolfram Alpha is bad at math).

My question is quite simple: Is there a real modulo operator in C# that I don't know of? Or do I have to write my own code for that?

All results I can find in the internet only point to the % ...

@Strikegently Thanks, I guess this work-around will work. So the answer is that there isn't an existing, build-in method for it? — Frederik Hoeft

@Strikegently that question is about C, not C#. See also % (mod) explanation, Why does the % operator sometimes output positive and sometimes negative?, How does modulus differ in C# vs. Excel? — phuclv

There is no modulo operator in c#.

The % operator, is the remainder operator:https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/arithmetic-operators#remainder-operator-

The remainder operator % computes the remainder after dividing its left-hand operand by its right-hand operand.
