foreach in async c# code example

Example: math.pow in C# using loop

static float CalculatePower(float x, int y)
        {
            float temp;
            if (y == 0)
                return 1;
            temp = CalculatePower(x, y / 2);
            if (y % 2 == 0)
                return temp * temp;
            else
            {
                if (y > 0)
                    return x * temp * temp;
                else
                    return (temp * temp) / x;
            }
        }
