REQUIRED INFORMATION

Ext version tested:

Ext 4.2.0

Browser versions tested against:

IE9
Chrome
FireFox

DOCTYPE tested against:

<!DOCTYPE html>

Description:

A number field subtracts or adds 1 from its value (odd only) on blur. It is, probably, related to JavaScript, but is there any chance to get it fixed?

Steps to reproduce the problem:

Copy/paste 9433381100915133 to the NumberField
Blur

The result that was expected:

The value does not change

The result that occurs instead:

Subtracts 1 => 9433381100915132

Test Case:

Code:

<!DOCTYPE html>
<html>
<head>
    <title>A number field subtracts or adds 1 from its value (odd only) on blur</title>

    <link rel="stylesheet" href="../resources/css/ext-all.css" />
    
    <script src="../ext-all-debug.js"></script>

    <script>
        Ext.onReady(function () {
            Ext.create("Ext.form.field.Number", {
                renderTo: Ext.getBody()     
            });
        });
    </script>
</head>
<body>

</body>
</html>

It's the behaviour of parseFloat:

Code:

console.log(parseFloat('9433381100915133'));

The only real solution would be to implement some kind of BigNumber library.

Could you implement, please? Just kidding.

Thank you for the answer.
