Last update on August 25 2025 12:48:52 (UTC/GMT +8 hours)

Write a C# Sharp program to get the absolute value of a number of Decimal values, Double values, Int16 values, Int32 values and Int64 values.

Sample Solution:

C# Sharp Code:

using System;
namespace exercises {
  class Program {
    static void Main(string[] args) {
      decimal[] decimals = {
        Decimal.MaxValue,
        15.55M,
        0M,
        -17.23M,
        Decimal.MinValue
      };
      Console.WriteLine("Absolute value of a number of Decimal values:");
      foreach(decimal value in decimals)
      Console.WriteLine($"Abs({value}) = {Math.Abs(value)}");
      double[] doubles = {
        Double.MaxValue,
        15.354e-17,
        14.098123,
        0,
        -17.069713,
        -14.058e18,
        Double.MinValue
      };
      Console.WriteLine("Absolute value of a number of Double values:");
      foreach(double value in doubles)
      Console.WriteLine($"Abs({value}) = {Math.Abs(value)}");
      short[] values1 = {
        Int16.MaxValue,
        10328,
        0,
        -1476,
        Int16.MinValue
      };
      Console.WriteLine("Absolute value of a number of Int16 values:");
      foreach(short value in values1) {
        try {
          Console.WriteLine($"Abs({value}) = {Math.Abs(value)}");
        } catch (OverflowException) {
          Console.WriteLine("Unable to calculate the absolute value of {0}.",
            value);
        }
      }
      Console.WriteLine("Absolute value of a number of Int32 values:");
      int[] values2 = {
        Int32.MaxValue,
        16921,
        0,
        -804128,
        Int32.MinValue
      };
      foreach(int value in values2) {
        try {
          Console.WriteLine($"Abs({value}) = {Math.Abs(value)}");
        } catch (OverflowException) {
          Console.WriteLine("Unable to calculate the absolute value of {0}.",
            value);
        }
      }

      long[] values3 = {
        Int64.MaxValue,
        109013,
        0,
        -6871982,
        Int64.MinValue
      };
      Console.WriteLine("Absolute value of a number of Int64 values:");
      foreach(long value in values3) {
        try {
          Console.WriteLine($"Abs({value}) = {Math.Abs(value)}");
        } catch (OverflowException) {
          Console.WriteLine("Unable to calculate the absolute value of {0}.",
            value);
        }
       }
      }
    }
  }

Sample Output:
