Decimal.Negate() Method in C#

Last Updated : 30 Jan, 2019

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

// 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

// 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.

// 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); 
    } 
}
