Java中的 BigInteger negate() 方法
先决条件:BigInteger 基础知识
Java.math.BigInteger.negate()方法返回一个 BigInteger,其值为 (-this)。 negate() 方法将改变 BigInteger 的单个位。
句法:
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。
例子:
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
下面的程序说明了 BigInteger 的 negate() 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
