Reverse method for Intl.NumberFormat
<p>I need to reverse the amount from formatted number according culture to double value in javascript.</p>

<p>By the use of Intl.NumberFormat method we change number to specific format according to culture. I want reverse method to convert formatted number to actual numeric value.
Example: new Intl.NumberFormat(window.navigator.language || window.navigator.userLanguage) </p>

<pre><code>var number = 123456.789;

// For German uses comma as decimal separator and period for thousands
console.log(new Intl.NumberFormat('de-DE').format(number));
// → 123.456,789

// For India uses thousands/lakh/crore separators
console.log(new Intl.NumberFormat('en-IN').format(number));
// → 1,23,456.789
</code></pre>

<p>Anybody having idea please suggest. </p>
