Java StrictMath cbrt()用法及代碼示例

java.lang.StrictMath.cbrt()是Java中的內置方法，用於返回給定double值的多維數據集根。該方法顯示三個特殊結果：

當給定參數為零時，結果為零，其符號與參數相同。
當參數為無窮大時，結果為無窮大且帶有相同的參數。
當給定參數為NaN時，結果為NaN。

用法:

public static double cbrt(double num)

參數：此方法接受一個參數num，該參數為double類型，需要找到其立方根。

返回值：該方法返回num的立方根。

下麵的程序演示了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); 
  
    } 
}

輸出：

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); 
  
    } 
}

輸出：

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