Java.lang.StrictMath.pow() Method

Description

The java.lang.StrictMath.pow() method returns the value of the first argument raised to the power of the second argument.It include these cases:

• If the second argument is positive or negative zero, returns 1.0.
• If the second argument is 1.0, returns the same as the first argument.
• If the second argument is NaN, returns NaN.
• If the first argument is NaN and the second argument is nonzero, returns NaN.

Declaration

Following is the declaration for java.lang.StrictMath.pow() method

public static double pow(double a, double b)

Parameters

• a -- This is the base

• b -- This is the exponent value.

Return Value

This method returns the the value a^b.

Exception

• NA

Example

The following example shows the usage of java.lang.StrictMath.pow() method.

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

  public static void main(String[] args) {
  
    double d1 = 4.5 , d2 = 6.9, d3 = 1;

    // returns d1 to the power d2
    double powValue = StrictMath.pow(d1 , d2); 
    System.out.println(""+ d1 + " to the power of " + d2 + " = " + powValue);
        
    // returns d1 to the power d3
    powValue = StrictMath.pow(d1 , d3); 
    System.out.println(""+ d1 + " to the power of " + d3 + " = " + powValue);
  }
}

Let us compile and run the above program, this will produce the following result:

4.5 to the power of 6.9 = 32148.916823357664
4.5 to the power of 1.0 = 4.5
