jQuery to allow only integers or floats in text input

Text input for integers and-or floats

//Select text inputs in container
//Highlight input text on focus
//Allow certain keys
$("#container-id input:text")
    .focus(function() {$(this).select();})
    .mouseup(function(e) {e.preventDefault();})
    .keydown(function (e) {
        //Allow: backspace, delete, tab, escape, enter, (decimal) and (period)
        //Only one '.' allowed
        //Adding data-nofloat='1' to element will disabled '.' for that input
        var allowArray = [46, 8, 9, 27, 13, 110, 190];
        if ($(this).data('nofloat') || $(this).val().indexOf('.') > -1) {
            //has data-nofloat='true' or already has a '.' in value
            //Remove last two codes (decimal and period)
            allowArray = allowArray.slice(0, 4);
        }
        if ($.inArray(e.keyCode, allowArray) !== -1 ||
            //Allow Ctrl+A (select all)
            (e.keyCode == 65 && e.ctrlKey === true) || 
            //Allow home, end, left, right
            (e.keyCode >= 35 && e.keyCode <= 39)) {
                //Do nothing
                return;
        }
        // Ensure that it is a number and stop the keypress
        if ((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
            e.preventDefault();
        }
    });
