Java BigDecimal intValueExact() Method

The intValueExact() method of java BigDecimal class is used to Convert a BigDecimal to an int type as well as this method also check for the lost information.

Syntax:

Parameter:

Exception:

If this has a non-zero fractional part, or will not fit in an int, then it throws an ArithmeticException.

Returns:

It returns int value from BigDecimal.

Example 1

import java.math.BigDecimal;  
public class BigDecimalIntValueExactExample1 {  
  
    public static void main(String[] args) {  
          
        // Creating BigDecimal Objects  
        BigDecimal bdValue;  
          
        //Create  int variable   
        int integerValue;  
          
        // Assigning value into BigDecimal object  
        bdValue = new BigDecimal("17674137");  
          
        //it returns integer value  
        integerValue=bdValue.intValueExact();  
          
        // Displaying exact Integer Value  
        System.out.println("Returned Exact Integer Value of " +bdValue + " is = " + integerValue);  
    }  
}  

Test it Now

Output:

Returned Exact Integer Value of 17674137 is = 17674137

Example 2

import java.math.BigDecimal;  
public class BigDecimalIntValueExactExample2 {

	public static void main(String[] args) {
		
        // Creating BigDecimal Objects
        BigDecimal bdValue;
        
        //Create  int variable 
        int integerValue;
        
        // Assigning value into BigDecimal object
        bdValue = new BigDecimal("-623341");
        
        //it returns integer value
        integerValue=bdValue.intValueExact();
        
        // Displaying exact Integer Value
        System.out.println("Returned Exact Integer Value of " +bdValue + " is = " + integerValue);
	}
}

Test it Now

Output:

Returned Exact Integer Value of -623341 is = -623341

Example 3

import java.math.BigDecimal;  
public class BigDecimalIntValueExactExample3 {

	public static void main(String[] args) {
		
        // Creating BigDecimal Objects
        BigDecimal bdValue;
        
        //Create  int variable 
        int integerValue;
        
        // Assigning value into BigDecimal object
        bdValue = new BigDecimal("55384629.32290");
        
        //it returns integer value
        integerValue=bdValue.intValueExact();

        // Displaying exact Integer Value
        System.out.println("Returned Exact Integer Value of " +bdValue + " is = " + integerValue);
	}
}

Test it Now

Output:

ArithmeticException

Example 4

  import java.math.BigDecimal;  
public class BigDecimalIntValueExactExample4 {

	public static void main(String[] args) {
		
        // Creating BigDecimal Objects
        BigDecimal bdValue;
        
        //Create  int variable 
        int integerValue;
        
        // Assigning value into BigDecimal object
        bdValue = new BigDecimal("74346789105829485");
        
        //it returns integer value
        integerValue=bdValue.intValueExact();
        
        // Displaying exact Integer Value
        System.out.println("Returned Exact Integer Value of " +bdValue + " is = " + integerValue);
	}
}
