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
