Java StrictMath cbrt()用法及代码示例

java.lang.StrictMath.cbrt()是Java中的内置方法，用于返回给定double值的多维数据集根。该方法显示三个特殊结果：

当给定参数为零时，结果为零，其符号与参数相同。
当参数为无穷大时，结果为无穷大且带有相同的参数。
当给定参数为NaN时，结果为NaN。

用法:

public static double cbrt(double num)

参数：此方法接受一个参数num，该参数为double类型，需要找到其立方根。

返回值：该方法返回num的立方根。

下面的程序演示了java.lang.StrictMath.cbrt()方法：
示例1:

// Java praogram to illustrate the 
// java.lang.StrictMath.cbrt() 
import java.lang.*; 
  
public class Geeks { 
  
    public static void main(String[] args) 
    { 
  
        double val1 = 8.05, val2 = 27, val3 = 0; 
  
        // It returns the cube root of a double value 
        double cbrtvalue = StrictMath.cbrt(val1); 
        System.out.println("Cube root of "+val1+ 
                                  " = " + cbrtvalue); 
  
        cbrtvalue = StrictMath.cbrt(val2); 
        System.out.println("Cube root of "+val2+ 
                                  " = " + cbrtvalue); 
  
  
        cbrtvalue = StrictMath.cbrt(val3); 
        System.out.println("Cube root of "+val3+ 
                                  " = " + cbrtvalue); 
  
    } 
}

输出：

Cube root of 8.05 = 2.0041580161269152
Cube root of 27.0 = 3.0
Cube root of 0.0 = 0.0

示例2:

// Java praogram to illustrate the 
// java.lang.StrictMath.cbrt() 
import java.lang.*; 
  
public class Geeks { 
  
    public static void main(String[] args) 
    { 
  
        double val1 = -8.05, val2 = 128, val3 = 0; 
  
        // It returns the cube root of a double value 
        double cbrtvalue = StrictMath.cbrt(val1); 
        System.out.println("Cube root of "+val1+ 
                                  " = " + cbrtvalue); 
  
        cbrtvalue = StrictMath.cbrt(val2); 
        System.out.println("Cube root of "+val2+ 
                                  " = " + cbrtvalue); 
  
        cbrtvalue = StrictMath.cbrt(val3); 
         System.out.println("Cube root of "+val3+ 
                                  " = " + cbrtvalue); 
  
    } 
}

输出：

Cube root of -8.05 = -2.0041580161269152
Cube root of 128.0 = 5.039684199579493
Cube root of 0.0 = 0.0
