BigDecimal intValue() Method in Java


The java.math.BigDecimal.intValue() is an in-built function which converts this BigDecimal to an integer value. This function discards any fractional part of this BigDecimal. If the result of the conversion is too big to be represented as an integer value, the function returns only the lower-order 32 bits.

Syntax:

public int intValue()

Parameters: This function accepts no parameters.



Return Value: This function returns the integer value of this BigDecimal.

Examples:

Input : 19878124.176
Output : 19878124

Input : "721111"
Output : 721111

        BigDecimal b1, b2;
        // Assigning values to b1, b2
        b1 = new BigDecimal("19878124.176");
        b2 = new BigDecimal("721111");
        // Displaying their respective Integer Values
        System.out.println("The Integer Value of " + b1 + " is " 
                                                + b1.intValue());
        System.out.println("The Integer Value of " + b2 + " is "
                                                + b2.intValue());
    }
}

Output:

The Integer Value of 19878124.176 is 19878124
The Integer Value of 721111 is 721111

Note: Information regarding the overall magnitude and precision of large this BigDecimal values might be lost during the course of conversion by this function. As a consequence, a result with the opposite sign might be returned.

Program 2: This program illustrates a scenario when the function returns a result with the opposite sign.
