round a number to the nearest hundredth in csharp

To round a number to the nearest hundredth in C#, you can use the built-in Math.Round method along with the MidpointRounding.ToEven enumeration value for the mode parameter. This is the default rounding mode that will round to the nearest even number when the value being rounded is exactly halfway between two potential rounding targets.

main.cs
decimal num = 1.23456m;
decimal roundedNum = Math.Round(num, 2, MidpointRounding.ToEven);
Console.WriteLine(roundedNum); // Outputs 1.23

The Math.Round method takes three parameters:

  • The number to be rounded (num)
  • The number of decimal places to round to (2 in this case for rounding to the nearest hundredth)
  • The rounding mode to use (MidpointRounding.ToEven)
