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 ab.

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
