# Convert to integer - Javascript

## How to convert a value to integer in javascript

Here I am going to show how to convert variable to integer in javascript.

DEMO

``````var a = "10";
var b = parseInt(a); ``````

Here variable a is a string, and b is an integer.  The data type of a variable is defined by the value in it.

So tho do mathematical operations like +,-,*,%,% etc... need to convert integer before doing it.

example

``````var a = "10";
var b= "20";
c = parseint(a)* parseint(b);
``````

Full Demo Code

``````<h1> Demo for conveting javascript to integer. </h1>
<input type="button" value="find sum" onclick = "findsum();"/> <br>

<script>
function findsum()
{

var a = "10";
var b= "20";
c = parseInt(a) * parseInt(b);

}
</script>``````
