Java.math.BigDecimal.longValue() Method
Description
The java.math.BigDecimal.longValue()converts this BigDecimal to an long.This conversion is analogous to the narrowing primitive conversion from double to short. Any fractional part of this BigDecimal will be discarded, and if the resulting "BigInteger" is too big to fit in an long, only the low-order 64 bits are returned.
This conversion can lose information about the overall magnitude and precision of this BigDecimal value as well as return a result with the opposite sign.
Declaration
Following is the declaration for java.math.BigDecimal.longValue() method.
public long longValue()
Specified by
longValue in class Number.
Parameters
NA
Return Value
This method returns the long value of the BigDecimal Object.
Exception
NA
Example
The following example shows the usage of math.BigDecimal.longValue() method.
package com.tutorialspoint; import java.math.*; public class BigDecimalDemo { public static void main(String[] args) { // create 2 BigDecimal objects BigDecimal bg1, bg2; // create 2 long objecs long l1,l2; bg1 = new BigDecimal("429.07"); bg2 = new BigDecimal("429496732223453626252"); // assign the long value of bg1 and bg2 to l1,l2 respectively l1 = bg1.longValue(); l2 = bg2.longValue(); String str1 = "long value of " + bg1 + " is " + l1; String str2 = "long value of " + bg2 + " is " + l2; // print l1,l2 values System.out.println( str1 ); System.out.println( str2 ); } }
Let us compile and run the above program, this will produce the following result −
long value of 429.07 is 429 long value of 429496732223453626252 is 5221618528133939084
