How do I turn a string to a number in JavaScript?

Question

I know one language uses tostring_i or something. Is there something like that in JavaScript? I'm trying to use JS to make something that uses a math formula to partition a segment.

Answer 1

Use the value attribute to get the value of the input element.

There are many ways to convert string to number in JavaScript. Some examples:

var str = "123.42"

parseInt(str) //123
parseFloat(str) //123.42
Number(str) //123.42
+str //123.42

Answer 2

I think I'll just try to make something where the user has to input the values, something still isn't working

Answer 3

"Use the value attribute to get the value of the input element."
I think I was not clear enough when i said that. What I meant:

var x = document.getElement....(input) // x is the HTMLInput element
var y = x.value // y is the value entered by user
