Java BigDecimal negate() method

The negate() method of java BigDecimal class is used to obtain a BigDecimal whose value is the negated value (-this) of the BigDecimal with which it is used.

Syntax:

public BigDecimal negate()
public BigDecimal negate(MathContext mc)

Parameter:

mc: the context to use.

Exception:

ArithmeticException- if the result is inexact but the rounding mode is UNNECESSARY, the it throws exception:

Returns:

It returns -this(negated BigDecimal value), rounded as necessary.

Example 1

import java.math.BigDecimal;  
public class BigdecimalNegateExample1 
{
	public static void main(String[] args) 
	{
	    // Creating  BigDecimal object
	    BigDecimal bdValue, negatedValue;
	       
	    // Assign value to BigDecimal objects
	    bdValue = new BigDecimal("5656");
	        
	    //it returns negated BigDecimal value
        negatedValue=bdValue.negate() ;
	        
        //Displaying negated value
	    System.out.println( "Negated value "+ bdValue +" is =  " +negatedValue );
	}
}

Test it Now

Output:

Negated value of 5656 is =  -5656

Example 2

import java.math.BigDecimal;  
public class BigdecimalNegateExample2 
{
	public static void main(String[] args) 
	{
	    // Creating  BigDecimal object
	    BigDecimal bdValue, negatedValue;
	       
	    // Assign value to BigDecimal objects
	    bdValue = new BigDecimal("-152207");
	        
	    //it returns negated BigDecimal value
	    negatedValue=bdValue.negate() ;
	    //Displaying negated value
	    System.out.println( "Negated value of  " +bdValue+"  is =  " +negatedValue );
	}
}

Test it Now

Output:

Negated value of  -152207  is =  152207

Example 3

import java.math.BigDecimal;  
import java.math.MathContext; 
public class BigdecimalNegateExample3 
{
	public static void main(String[] args) 
	{
	        // Creating  BigDecimal object
	        BigDecimal bdValue, negatedValue;
	       
	        // Assign value to BigDecimal objects
	        bdValue = new BigDecimal("-18.5414");
	        
	        // Assigning value in MathContext object
	        MathContext mc = new MathContext(4); 
	        
	        //it returns negated BigDecimal value
	        negatedValue=bdValue.negate(mc) ;
	        //Displaying negated value
	        System.out.println( "Negated value of  " +bdValue+" rounded by 4  is =  " +negatedValue );
	}
}

Test it Now

Output:

Negated value of  -18.5414 rounded by 4  is =  18.54

Example 4

import java.math.BigDecimal;  
import java.math.MathContext; 
public class BigdecimalNegateExample4 {

	public static void main(String[] args) {
		
	      // Creating  BigDecimal object
	        BigDecimal bdValue, negatedValue;
	       
	      // Assign value to BigDecimal objects
	        bdValue = new BigDecimal("-178901456.68431");
	        
	        // Assigning value in MathContext object
	        MathContext mc = new MathContext(16); 
	        
	        //it returns negated BigDecimal value
	        negatedValue=bdValue.negate(mc) ;
	        //Displaying negated value
	       System.out.println( "Negated value of  " +bdValue+" rounded by 16  is =  " +negatedValue );
	}
}

Test it Now

Output:

Negated value of  -178901456.68431 rounded by 16  is =  178901456.68431
