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

 

Module Example
   Public Sub Main()
      Dim values() As Double = { 2.125, 2.135 }
      For Each value As Double In values
         Console.WriteLine("{0} --> {1}", value, Math.Round(value, 2))
      Next
   End Sub
End Module
