toString and valueOf truncates trailing 0s after decimal

I have a number, 2.0e-14, and I want to convert it to string. I'm using (2.0e-14).toString(), and what I get is the string 2e-14, because it's removing the zeroes at the right.
Is there any way of keep the zero at the right than to manipulating the string?
Use the Number toPrecision method.
(2.0e-14).toPrecision(2)

let string = "13th"
string = Number(string)
I expect it to return 13 instead I get NaN please how do I go about it
Try with parseInt()
If parseInt encounters a character that is not a numeral in the specified radix, it ignores it and all succeeding characters and returns the integer value parsed up to that point. parseInt truncates numbers to integer values. Leading and trailing spaces are allowed.
let string = "13th";
string = parseInt(string);
console.log(string);

Here is my string: "6145390195186705543"
I have tried parseInt with different radix values. I have tried the Number() method. And I have tried multiplying it by one. They all give back 6145390195186705000
Why is this??

I have a string like 12345 and I need to explode it to [1,2,3,4,5]. Normally, I would use split, but there are no separators in here. I could use substr (getting length, making loops), but I will probably have a lot of those strings, so it may not be good for performance. What can I do?
Simply use an empty string as a delimiter:
"12345".split('');

So I saw this strange scenario. I wanted to convert a number to a String in Node.js and I got the following.
01010100132.toString()
Turns into
"136347738"
Can someone explain this to me?
Any numeric constant prefixed with a 0 is an octal literal (assuming all its digits are valid octal digits).
var i = 010; // 8 decimal

I have used document.getElementByID("textboxname").value to compare but it checks character by character as it considers integer value a string value.
I like to know how to convert document.getElementByID("textboxname").value string notation to integer notation so that it will be easy to compare integer values.
Thanks in advance
use parseInt("your string") to convert it into valid integer
Use parseInt(document.getElementByID("textboxname").value, 10);
