How to convert a string into float using JavaScript?

Convert String Into Float Using JavaScript:

Suppose we have a value that contains coma like 200,52600 then how to convert this string value to the float in javascript.

Replace the comma with a dot then it will be able to convert into a float value by using javascript.

var value = parseFloat("200,52600");
This will only return 200:

var value = parseFloat("200,52600");
This will return 200.52600:

So in the end, we can simply use below code.
var fValue = parseFloat(document.getElementById("textfieldid").value.replace(",","."))

Do not forget that parseInt() should only be used to parse integers (no floating points). In this case it will only return 200. Additionally, calling parseInt() on a float will not round the number: it will take its floor (closest lower integer).
