# C# - Math.Abs() Method with Example

In this tutorial, we will learn about the C# Math.Abs() method with its definition, usage, syntax, overload, and example. By Nidhi Last updated : March 29, 2023

## C# Math.Abs() Method

The Math.Abs() method is used to return the absolute value of a given value. It means if we pass a positive value then it returns a positive value and if pass a negative value then it will also return a positive value.

There are the following overloaded method used to get absolute value,

```Math.Abs(Decimal)
Math.Abs(Double)
Math.Abs(Int16)
Math.Abs(Int32)
Math.Abs(Int64)
Math.Abs(SByte)
Math.Abs(Single)
```

All the above-overloaded methods return value according to the type passed as a parameter.

We will understand all overloaded method with the help of program.

## C# Example of Math.Abs() Method

The source code to demonstrate the use of Abs() method of Math class is given below. The given program is compiled and executed successfully.

```using System;
using System.IO;

class Sample {
//Entry point of Program
static public void Main() {
double[] doubles = {
Double.MaxValue,
Double.MinValue,
157.37,
120.00,
-5.96
};
decimal[] decimals = {
Decimal.MaxValue,
Decimal.MinValue,
157.37M,
120.00M,
-5.96M
};

int[] integers = {
Int32.MaxValue,
Int32.MinValue,
157,
120,
-5
};

Console.WriteLine("Double Values:");
foreach(double VAL in doubles)
Console.WriteLine("\tMath.Abs({0}) : {1}", VAL, Math.Abs(VAL));

Console.WriteLine("\nDecimal Values:");
foreach(decimal VAL in decimals)
Console.WriteLine("\tMath.Abs({0}) : {1}", VAL, Math.Abs(VAL));

Console.WriteLine("\nInteger Values:");
foreach(decimal VAL in integers)
Console.WriteLine("\tMath.Abs({0}) : {1}", VAL, Math.Abs(VAL));
}
}
```

## Output

```Double Values:
Math.Abs(1.79769313486232E+308) : 1.79769313486232E+308
Math.Abs(-1.79769313486232E+308) : 1.79769313486232E+308
Math.Abs(157.37) : 157.37
Math.Abs(120) : 120
Math.Abs(-5.96) : 5.96

Decimal Values:
Math.Abs(79228162514264337593543950335) : 79228162514264337593543950335
Math.Abs(-79228162514264337593543950335) : 79228162514264337593543950335

Math.Abs(157.37) : 157.37
Math.Abs(120.00) : 120.00
Math.Abs(-5.96) : 5.96

Integer Values:
Math.Abs(2147483647) : 2147483647
Math.Abs(-2147483648) : 2147483648
Math.Abs(157) : 157
Math.Abs(120) : 120
Math.Abs(-5) : 5
