我们可以使用Math.log10()和Math.log()静态方法调用来计算对数。
package org.nhooo.example.math; public class LogarithmExample { public static void main(String[] args) { double number1 = 1000.0d; // 获取常用对数 double log10 = Math.log10(number1); System.out.println("Common logarithm of " + number1 + " = " + log10); // 获取自然对数 double loge = Math.log(number1); System.out.println("Natural logarithm of " + number1 + " = " + loge); } }
该程序的输出为:
Common logarithm of 1000.0 = 3.0 Natural logarithm of 1000.0 = 6.907755278982137
