Hexadecimal to binary in Nodejs

Question

I have this hexadecimal in a nodejs Tcp Client

82380000000000000400000000000000

I have used parseint function to convert it to

1.73090408076117e+38

But i need to get its binary representation that is

10000010001110000000000000000000000000000000000000000000000000000000010000000000000000000000000000000000000000000000000000000000

Ho can i get this binary representation from the above hexadecimal format?

Answer 1

Using the toString specifying the base as the parameter should make it. For example, if you want to convert it to a binary string, after parsing it to an integer:

var number = '82380000000000000400000000000000';
console.log(parseInt(number).toString(2));

In case you want an hexadecimal string, just use .toString(16);

If you don't want to parse the string with the number:

var number = 82380000000000000400000000000000;
console.log(number.toString(2));

Hope this helps.
