numberSeparators.js

    // defaults
    var res = { "decimal": ".", "thousand": "" };

    // convert a number formatted according to locale
    var str = parseFloat(1234.56).toLocaleString(locale);

    // if the resulting number does not contain previous number
    // (i.e. in some Arabic formats), return defaults

    // get decimal and thousand separators
    res.decimal = str.replace(/.*4(.*)5.*/, "$1");
    res.thousand = str.replace(/.*1(.*)2.*/, "$1");
