Easy and Flexible Hexadecimal Conversion in JavaScript

Recently, I came across someone asking about converting a number to its hexadecimal equivalent using JavaScript. I just thought of sharing what I helped them with other readers since it involves a very simple function toString() in JavaScript but lesser known to all.

The following simple code snippet demonstrates the ease of conversion of decimal to hexadecimal in JavaScript:

<script language='Javascript'>
var intSrc = 25;
alert (intSrc.toString(16));
</script>

Other conversions:
  1. toString(2) establishes decimal to binary conversion
  2. toString(8) achieves decimal to octal conversion
