Decimal.Negate() Method in C#

Last Updated : 11 Jul, 2025

This method is used to get the result of multiplying the specified Decimal value by negative one.

Syntax: public static decimal Negate (decimal a); Parameter: a: This parameter specifies the decimal which will be converted. Return Value: A decimal number with the value of a, but the opposite sign. But zero, if a is zero.

Below programs illustrate the use of Decimal.Negate(Decimal) Method: Example 1: When a is positive

csharp

// C# program to demonstrate the
// Decimal.Negate(Decimal) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring the decimal variable
        Decimal a = 127.97m;

        // using Negate() method;
        Decimal value = Decimal.Negate(a);

        // Display the negative value
        Console.WriteLine("The negative value "+
                             "is : {0}", value);
    }
}

Output:

The negative value is : -127.97

Example 2: When a is negative

csharp

// C# program to demonstrate the
// Decimal.Negate(Decimal) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring the decimal variable
        Decimal a = -12.39m;

        // using Negate() method;
        Decimal value = Decimal.Negate(a);

        // Display the value after
        // using negate method
        Console.WriteLine("The value is : {0}",
                                        value);
    }
}

Output:

The value is : 12.39

Example 3: If a is zero.

csharp

// C# program to demonstrate the
// Decimal.Negate(Decimal) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring the decimal variable
        Decimal a = 0.00m;

        // using Negate() method;
        Decimal value = Decimal.Negate(a);

        // Display the Negate value
        Console.WriteLine("The Negate value "+
                           "is : {0}", value);
    }
}
