How to convert floating number to string array in Javascript?

Question

I need to convert a floating number to a string array, for example var num=25.67 into var str_array[0] = '2', str_array[1]='5', str_array[2]='.', str[3]='6'; str_array[4]='7' . Please show your code. Thank you very in advance.

It's easy. You just have to convert the num var into an string (with the .toString() method) and then .split('') it (the '' parameter makes it split every character).

var num = 25.67;
var str_array = num.toString().split('');

You can also use this code:

var num = 25.67;
var str_array = num.toString();

Then str_array will be no more an array, but a string (which can be treated as an array)

"Treated as an array" - No, a string does not inherit methods from Array.prototype. Though it does have numeric keys which act like .charAt().

What I mean is that you can access a character from a string using square brackets like you do when you wanna access an item of an array

Try with

var digits = num.toString().split('');
