Usage of Math functions in Java

               Math Functions for use in Java

Some useful terms for proceeding further.

Program : Program is a set of Instructions given to a computer to perform a specific task.

Package : Package is a collection of classes to perform various functions.

In Java every package has a name and it can be included within a program by using the keyword “import”.

For now let us consider the following functions in the Math package of Java. Note that many of the Math functions are called automatically by the system(by default) to perform the desired task.

(1) Math.sqrt(): This function is used to find the square root of the given number.

Ex: num=Math.sqrt(9);

     So the value of the num will be 3.

(2) Math.pow(): This function is used to find the power raised to a specified base.

Ex: num=Math.pow(2,3);

      So the value of the num is 2^3=8

The above example is just to show how we use the math functions. We will explore more math functions in further posts.

In next post we will cover the use of Classes in Java and also the creation and use of objects in Java.
