Java中的BigInteger否定()方法

先决条件: 大整数基础 这个 JAVA数学大整数。否定 方法返回一个BigInteger,其值为(-this)。方法将更改BigInteger的单个位。

语法:

public BigInteger negate()

参数: 该方法不接受任何参数。

返回值: 该方法返回(-this)的操作。

例如:

Input: value = 2300
Output: -2300
Explanation:
Binary signed 2's complement of 2300 = 0000100011111100
Singed bit are 0000
change sing bit to 1111
so negate of 0000100011111100 in signed 2's complement is 1111011100000100
Decimal value = -2300.

Input: value = 567689 
Output: -567689 

下面的程序演示了BigInteger的否定()方法。

/*
*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);
}
}


输出:

Result of negate operation on 2300 is -2300
