How do I create a rule for only positive whole numbers greater then 0 (ex. 1,2,3,4,5,etc)?

```js
var form = $('#formClientLicense')[0];
$(form).validate();

var quantity = $(form).find("input[name='Quantity']")[0];
$(quantity).rules("add", {
    required: true,
    min: 1,
    step: 1,
    number: true,
    messages: {
        required: jQuery.validator.format("Required Field"),
        number: "Not a number",
        min: jQuery.validator.format("Please select positive number"),
        step: jQuery.validator.format("Please select whole number (ex. 1,2,3,4)")
    }
});

if ($(form).valid()) {
    // run here
}

```
