How to convert a string to number?

Question

Ex.
var a = 1.1.06

How can the string be converted to number?

Also, how can I altogether convert the strings in an array into numbers?
ex . array = [1.0.5, 1.1.2, 1.2.5]
Into(expected output) array = [105, 112, 125]

Answer 1

1.1.06 is not a valid numeric value. Even if you try, converting it from a string "1.1.06" to a number, you most likely will get a NaN (not a number).

(Edit)
If you use parseInt() then you get 1 (one) only. Any character following the '.' will be ignored.

Answer 2

Pradnya Meshram ,

can you please give a sample what you expect as output when using "1.1.06" as input?

Answer 3

it can be also be one by using split(), then join() and finally convert the result to int:

var myString = '1.1.06';
var n = parseInt(myString.split(".").join(""));
console.log(n)

Answer 4

You can use the String method replace/replaceAll wrapped in parseInt method.

ex: let test = '1.1.06'
let num = parseInt(test.replaceAll(/\D/,""))

I'm not sure if it's possible, but I'm expecting an output removing the dots
ex. If the value is 1.1.06
I want the output as 1106

Take a look at this.

const nameLengths = names.map(function (name) { return name.length;
});
nameLengths; //output [5,8]
