Consider using $.map instead of $.each:

    var cosPoints = $('#textfield1').val().split(',');
    var arrayPoints = $.map(cosPoints, function (str) {
        return parseFloat(str);
    });

Or, using plain ES 5.1:

    var arrayPoints = cosPoints.map(function (str) {
        return parseFloat(str);
    });
