Hello readers in this blog we will discuss about the conversion of a decimal into a hexadecimal value. In this case if we have a decimal value. we have to find its hexadecimal equivalent, we use the Number object’s toString method :-

Syntax:-

var num = 255;
alert(num.toString(16)); // displays ff, which is hexadecimal equivalent for 255

The default javascript numbers are base 10, or deciaml. hexadecimal and octal notation can be used and created.

 Hexadecimal numbers begin with 0x (a zero followed by lowercase x), and octal numbers always begin with zero:
 

Syntax:-

var octoNumber = 0255; // equivalent to 173 decimal
var hexaNumber = 0xad; // equivalent to 173 decimal

By using the Number object’s toString method other base numbers can be created. By passing in the base radix, in a range from 2 to 36:

Syntax:-

var decNum = 55;
var octNum = decNum.toString(8); // value of 67 octal
var hexNum = decNum.toString(16); // value of 37 hexadecimal
var binNum = decNum.toString(2); // value of 110111 binary

You need to concentrate the zero to the octal, and the 0x to the hexadecimal value if you want to complete the octal and hexadecimal presentation. Base number (between a range of 2 to 36) can be changed over by decimals just the octal, hexadecimal, and decimal numbers can be controlled, straightforwardly, as numbers.
