I have been trying to improve (i.e., "idiot-proof") the edit dialogs of some contributed nodes, and it would help to have more information about the `input type="number"` tag. As far as I have found, the official [documentation](https://nodered.org/docs/creating-nodes/edit-dialog) refers only to the `text`, `checkbox`, and `select` types. A number of core and contributed nodes (including my own) use the `number` type more or less successfully, but the documentation refers to using `text` for "string/number properties". Does that mean that the use of `number` is discouraged?

It isn't discouraged... Just wasn't really on my radar when I wrote those docs.

Thanks, Nick. I really don't expect you to write documentation just now. I'm mainly interested in writing a few validation functions for this widget, but its behavior seems a bit odd at times. If it's not too much trouble, can you point me to the source for it?

`<input type="number">` is an HTML5 standard element - [\<input type="number"\> - HTML: HyperText Markup Language | MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/number)

Well, that shows how long I've been at this. Does that mean it can be used with the other attributes (like `max` and `min`) in the edit dialog?
