How to convert a string to number

Question

I can't figure it out how to convert this string 82144251 to a number.

Code:

var num = "82144251"; 

If I try the code below the .toFixed() function converts my number back to a string...

Question update: I'm using the Google Apps Script editor and that must be the issue...

num = parseInt(num).toFixed() // if I just do parseInt(num) it returns 8.2144251E7 

Answer 1

You can convert a string to number using unary operator '+' or parseInt(number,10) or Number()

check these snippets

var num1a = "1";  console.log(+num1a);    var num1b = "2";  num1b=+num1b;  console.log(num1b);      var num3 = "3"  console.log(parseInt(num3,10));      var num4 = "4";  console.log(Number(num4));

Hope it helps

Answer 2

It looks like you're looking for the Number() functionality here:

var num = "82144251"; // "82144251" var numAsNumber = Number(num); // prints 82144251 typeof num // string typeof numAsNumber // number
