Beispiele

Im folgenden Beispiel wird die Abs(Decimal)-Methode verwendet, um den absoluten Wert einer Reihe von Decimal Werten zu erhalten.The following example uses the Abs(Decimal) method to get the absolute value of a number of Decimal values.

decimal[] decimals = { Decimal.MaxValue, 12.45M, 0M, -19.69M, 
                       Decimal.MinValue };
foreach (decimal value in decimals)
   Console.WriteLine($"Abs({value}) = {Math.Abs(value)}");

// The example displays the following output:
//       Abs(79228162514264337593543950335) = 79228162514264337593543950335
//       Abs(12.45) = 12.45
