I am interested in how to round variables to two decimal places. In the example below, the bonus is usually a number with four decimal places. Is there any way to ensure the pay variable is always rounded to two decimal places?

  pay = 200 + bonus;
  Console.WriteLine(pay);

Rounds a double-precision floating-point value to a specified number of fractional digits.

Or Math.Round Method (Decimal, Int32)
