Prerequisite: BigInteger Basics The java.math.BigInteger.negate() method returns a BigInteger whose value is (- this). negate() method will change the signed bit of BigInteger. Syntax:
public BigInteger negate()
Parameters: The method does not accept any parameter. Return Value: The method returns the operation of (- this). Examples:
Input: value = 2300 Output: -2300 Explanation: Binary signed 2's complement of 2300 = 0000100011111100 Signed bit are 0000 change sign bit to 1111 so negate of 0000100011111100 in signed 2's complement is 1111011100000100 Decimal value = -2300. Input: value = 567689 Output: -567689
Below program illustrates negate() method of BigInteger.
Java
/**Program Demonstrate negate() method of BigInteger*/import java.math.*;public class GFG { public static void main(String[] args) { // Create BigInteger object BigInteger biginteger = new BigInteger("2300"); // Call negate() method to find -this BigInteger finalvalue = biginteger.negate(); String result = "Result of negate operation on " + biginteger + " is " + finalvalue; // Prints result System.out.println(result); }} |
Output:
Result of negate operation on 2300 is -2300
