C# | Math.Abs() Method | Set - 1 Last Updated : 01 Feb, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report In C#, Abs() is a Math class method which is used to return the absolute value of a specified number. This method can be overload by passing the different type of parameters to it. Math.Abs(Decimal) Math.Abs(Double) Math.Abs(Int16) Math.Abs(Int32) Math.Abs(Int64) Math.Abs(SByte) Math.Abs(Single) Math.Abs(Decimal) This method is used to return the absolute value of a Decimal number. Syntax: public static decimal Abs (decimal val); Parameter: val: It is the required number which is greater than or equal to Decimal.MinValue, but less than or equal to Decimal.MaxValue of type System.Decimal. Return Type: It returns a decimal number say r, such that 0 ≤ r ≤ Decimal.MaxValue. Example: CSharp // C# Program to illlustrate the // Math.Abs(Decimal) Method using System; class Geeks { // Main Method public static void Main() { // Taking decimal values decimal[] deci = {Decimal.MinValue, 45.14M, 0M, -17.47M, Decimal.MaxValue}; // using foreach loop foreach(decimal value in deci) // Displaying the result Console.WriteLine("Absolute value of {0} = {1}", value, Math.Abs(value)); } } Output: Absolute value of -79228162514264337593543950335 = 79228162514264337593543950335 Absolute value of 45.14 = 45.14 Absolute value of 0 = 0 Absolute value of -17.47 = 17.47 Absolute value of 79228162514264337593543950335 = 79228162514264337593543950335 Math.Abs(Double) This method is used to return the absolute value of a double-precision floating-point number. Syntax: public static double Abs (double val); Parameter: val: It is the required number which is greater than or equal to Double.MinValue, but less than or equal to Double.MaxValue of type System.Double. Return Type: It returns a double-precision floating-point number say r, such that 0 ≤ r ≤ Double.MaxValue. Note: If val is equal to NegativeInfinity or PositiveInfinity, the return value will be PositiveInfinity. If the val is equal to NaN then return value will be NaN. Example: CSharp // C# Program to illlustrate the // Math.Abs(Double) Method using System; class Geeks { // Main Method public static void Main() { // Taking a NaN Double nan = Double.NaN; // Taking double values double[] doub = {Double.MinValue, 27.58, 0.0, 56.48e10, nan, Double.MaxValue}; // using foreach loop foreach(double value in doub) // Displaying the result Console.WriteLine("Absolute value of {0} = {1}", value, Math.Abs(value)); } } Output: Absolute value of -1.79769313486232E+308 = 1.79769313486232E+308 Absolute value of 27.58 = 27.58 Absolute value of 0 = 0 Absolute value of 564800000000 = 564800000000 Absolute value of NaN = NaN Absolute value of 1.79769313486232E+308 = 1.79769313486232E+308 Math.Abs(Int16) This method is used to return the absolute value of a 16-bit signed integer. Syntax: public static short Abs (short val); Parameter: val: It is the required number which is greater than Int16.MinValue, but less than or equal to Int16.MaxValue of type System.Int16. Return Type: It returns 16-bit signed integer say r, such that 0 ≤ r ≤ Int16.MaxValue. Exception: This method will give OverflowException if the value of val is equals to Int16.MinValue. Example: CSharp // C# Program to illlustrate the // Math.Abs(Int16) Method using System; class Geeks { // Main Method public static void Main() { // Taking short values short[] sh = {Int16.MaxValue, 1482, -142, 0 }; // using foreach loop foreach(short value in sh) // Displaying the result Console.WriteLine("Absolute value of {0} = {1}", value, Math.Abs(value)); } } Output: Absolute value of 32767 = 32767 Absolute value of 1482 = 1482 Absolute value of -142 = 142 Absolute value of 0 = 0 Math.Abs(Int32) This method is used to return the absolute value of a 32-bit signed integer. Syntax: public static int Abs (int val); Parameter: val: It is the required number which is greater than Int32.MinValue, but less than or equal to Int32.MaxValue of type System.Int32. Return Type: It returns 32-bit signed integer say r, such that 0 ≤ r ≤ Int32.MaxValue. Exception: This method will give OverflowException if the value of val is equals to Int32.MinValue. Example: CSharp // C# Program to illlustrate the // Math.Abs(Int32) Method using System; class Geeks { // Main Method public static void Main() { // Taking int values int[] int_val = {Int32.MaxValue, 13482, -65525, 0}; // using foreach loop foreach(int value in int_val) // Displaying the result Console.WriteLine("Absolute value of {0} = {1}", value, Math.Abs(value)); } } Output: Absolute value of 2147483647 = 2147483647 Absolute value of 13482 = 13482 Absolute value of -65525 = 65525 Absolute value of 0 = 0 There are total 7 methods in its overload list.
