In a part of my code I have to check if a number entered by the user is greater than a maximum. I have this written:

```
console.log("mod: "+ mod);
console.log("max_mod: "+ max_mod);
console.log("mod > max_mod: "+ (mod > max_mod));
```

When I write 2 or a number between 2 and 9 the result of the console.log is as follows:

- mod: 2
- max_mod: 12
- mod > max_mod: true

However, if I write 1, 10 or 11 the result is this, which is normal:

- mod: 1
- max_mod: 12
- mod > max_mod: false

I do not know why this happens, the numbers I pick up from different variables like this:

```
var mod = $(this).parents(".modal-content").find("#input_num_mod").val();
var max_mod = $(this).parents(".modal-content").attr('data_mod');
```

Does anyone know why this may be happening?
