Java Exponents: How To Find Exponents Of A Number In Java

Posted by

Are you facing challenges in solving the problem of calculating exponent in Java? First of all, you can’t find it. Java doesn’t feature exponent operator like some other programming languages. Still, you can use the standard mathematical operations features in Java called Math static class in Java .util.Math. You can also use some supported operations such as rounding exponents, standard trigonometric functions, and those for finding absolute value. The output of these mathematical operations are usually close “double” data-types, yet you can convert them to floats and integers where necessary.

Exceptional Cases To Be Considering When Using The Pow () Exponents Method In Java

You need to considering the following rules while using the pow () Java exponent:

  1. Suppose the second number is zero, either positive or negative, then the result would be 1.0.
  2. Assuming the second number is one, then the value would be the same as the first number.
  3. If the second parameter is P, then the output would be the same.

Let’s move ahead to how to do exponents in Java.

How To Do Exponents In Java

You need to perform the following to do exponents in Java:

  • Launch the Netbeans Integrated Development Environment, or IDE, or use any Java editor of your choice.
  • Create a new Java source file or launch an existing one by tapping on “File” and “New Class.”
  • Type the following statement to the header of the document:

 import java.until.Math

  • Type the following command statement in the document to find an exponent: 

double result = Math.pow(number, exponent);

Change the “number” with the base value and the “exponent” with the corresponding exponent value said to be raised.

The following are the potential example to find exponents in Java as follows:

Example 1: 

double result = Math.pow(2,3)

The output result after the execution is 8, or 2^3

Example 2: 

Double exp2 = Math.exp (2);
System.out.println(“exp1 = ” + exp2);

Double exp2 = Math.exp(2);
System.out.println(“exp2= ” + exp2);

The result for the above statement after the execution would be:

For exp1 = 2.718281828459045

For exp2 = 7.38905609893065

These are the way you can use to find exponents in Java after the execution of the stated statement above.
