Description

The java.math.BigDecimal.toBigIntegerExact() converts this BigDecimal to a BigInteger, checking for lost information. An exception is thrown if this BigDecimal has a nonzero fractional part.

Declaration

Following is the declaration for java.math.BigDecimal.toBigIntegerExact() method.

public BigInteger toBigIntegerExact()

Parameters

NA

Return Value

This method returns the value of BigDecimal object converted to a BigInteger.

Exception

ArithmeticException − If this has a nonzero fractional part.

Example

The following example shows the usage of math.BigDecimal.toBigIntegerExact() method.

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

   public static void main(String[] args) {

      // create a BigDecimal object
      BigDecimal bg1;
   
      // create a BigInteger object
      BigInteger i1;

      bg1 = new BigDecimal("2426");

      // assign the BigIntegerExact value of bg1 to i1
      i1 = bg1.toBigIntegerExact();

      String str = "BigInteger value of " + bg1 + " is " + i1;

      // print i1 value
      System.out.println( str );
   }
}

Let us compile and run the above program, this will produce the following result −

BigInteger value of 2426 is 2426
