Java如何对BigDecimal进行数学运算？
package org.nhooo.example.math;
import java.math.BigDecimal;
import java.math.RoundingMode;
public class BigDecimalOperation {
public static void main(String[] args) {
BigDecimal decimalA = new BigDecimal("98765432123456789");
BigDecimal decimalB = new BigDecimal("10");
decimalA = decimalA.add(decimalB);
System.out.println("decimalA = " + decimalA);
decimalA = decimalA.multiply(decimalB);
System.out.println("decimalA = " + decimalA);
decimalA = decimalA.subtract(decimalB);
System.out.println("decimalA = " + decimalA);
decimalA = decimalA.divide(decimalB, RoundingMode.DOWN);
System.out.println("decimalA = " + decimalA);
decimalA = decimalA.pow(2);
System.out.println("decimalA = " + decimalA);
decimalA = decimalA.negate();
System.out.println("decimalA = " + decimalA);
}
}我们的代码片段结果是：
decimalA = 98765432123456799 decimalA = 987654321234567990 decimalA = 987654321234567980 decimalA = 98765432123456798 decimalA = 9754610582533151990855052972412804 decimalA = -9754610582533151990855052972412804
