How to convert a currency string to a double with jQuery or Javascript

Question

I have a text box that will have a currency string in it that I then need to convert that string to a double to perform some operations on it      1 100 00    1100 00  This needs to occur all client side  I have no choice but to leave the currency string as a currency string as input but need to cast convert it to a double to allow some mathematical operations

This function should work whichever the locale and currency settings :

function getNumPrice(price, decimalpoint) {
    var p = price.split(decimalpoint);
    for (var i=0;i<p.length;i++) p[i] = p[i].replace(/\D/g,'');
    return p.join('.');
}

This assumes you know the decimal point character (in my case the locale is set from PHP, so I get it with <?php echo cms_function_to_get_decimal_point(); ?>).

I know this is an old question but wanted to give an additional option    The jQuery Globalize gives the ability to parse a culture specific format to a float    https   github com jquery globalize  Given a string   13 042 00   and Globalize set to en-US   Globalize culture  en-US      You can parse the float value out like so   var result   Globalize parseFloat Globalize format   13 042 00    c       This will give you   13042 00   And allows you to work with other cultures

Use a regex to remove the formating  dollar and comma   and use parseFloat to convert the string to a floating point number    var currency     1 100 00   currency replace        g      var result   parseFloat currency     05

150 00     Fr  150 00         689 00   I have tested for above three currency symbols  You can do it for others also       var price   Fr  150 00      var priceFloat   price replace     d    g         Above regular expression will remove everything that is not a digit or a period So You can get the string without currency symbol but in case of   Fr  150 00   if you console for output then you will get price as      console log  priceFloat     priceFloat        output will be like  priceFloat    150 00   which is wrong so you check the index of     then split that and get the proper result       if  priceFloat indexOf         0                priceFloat   parseFloat priceFloat split      1         else              priceFloat   parseFloat priceFloat

I know this is an old question  but CMS s answer seems to have one tiny little flaw  it only works if currency format uses     as decimal separator  For example  if you need to work with russian rubles  the string will look like this    1 000 00 rub    My solution is far less elegant than CMS s  but it should do the trick     x000D   x000D  var currency    1 000 00 rub      it works for US-style currency strings as well x000D  var cur re     D   d   d    d     D   d 2     D     x000D  var parts   cur re exec currency   x000D  var number   parseFloat parts 1  replace   D           parts 2  parts 2   00     x000D  console log number toFixed 2    x000D   x000D   x000D    Assumptions    currency value uses decimal notation there are no digits in the string that are not a part of the currency value currency value contains either 0 or 2 digits in its fractional part     The regexp can even handle something like  1 999 dollars and 99 cents   though it isn t an intended feature and it should not be relied upon   Hope this will help someone
