Question

Prev = 10, Cur = 17, Step = 2.

Is there a method that will give me Prev + Step (or Prev - Step in case Prev > Cur)?

UPD: I’m looking for something like this:

int StepDifference(int A, int B, int N)
        {
            int ret;
            if (A > B)
                if (A - N >= B)
                    ret = A - N;
                else
                    ret = B;
            else
                if (A + N <= B)
                    ret = A + N;
                else
                    ret = B;
            return ret;
        }

Is there an “official” method in Math or other namespaces? I’m going to do this a lot and It could be slower with a custom implementation, I think. Almost every custom implementation of an “official” helper method I tried is slower, that’s why I’m asking.

Answer 1

There is no such method in any Microsoft namespace.
