Advertisements

## Description

The java.math.BigDecimal.intValueExact()converts this BigDecimal to an int, checking for lost information. If this BigDecimal has a nonzero fractional part or is out of the possible range for an int result then an ArithmeticException is thrown.

## Declaration

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

```public int intValueExact()
```

NA

## Return Value

This method returns the int value of the BigDecimal Object.

## Exception

ArithmeticException − If this has a nonzero fractional part, or will not fit in an int.

## Example

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

```package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

public static void main(String[] args) {

// create 2 BigDecimal objects
BigDecimal bg1, bg2;

//Create two int Object
int i1, i2;

bg1 = new BigDecimal("40");
bg2 = new BigDecimal("4E+1");

// assign the exact int value of bg1 and bg2 to i1,i2 respectively
i1 = bg1.intValueExact();
i2 = bg2.intValueExact();

String str1 = "Exact int value of " + bg1 + " is " + i1;
String str2 = "Exact int value of " + bg2 + " is " + i2;

// print i1,i2 values
System.out.println( str1 );
System.out.println( str2 );
}
}
```

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

```Exact int value of 40 is 40
Exact int value of 4E+1 is 40
```
