- It has a form to edit numeric data. The input fields are type="text".
- There's a function to convert numbers from internal to German (, instead of .)
- There's a function to convert it back
- There are event handlers to do the conversion for each text input
I removed all of that and changed the text field type to "number".
edit: I should've mentioned that this is Vue with Bootstrap, and the input component isn't a plain <input>
