I think type=number is a mistake as it is too generic. It is difficult to get proper validation, UI and error messages. It should be split into: type=integer

I think type=number is a mistake as it is too generic. It is difficult to get proper validation, UI and error messages. It should be split into: type=integer so the keyboard does not allow anything besides 0-9 type=decimal so the keyboard also allows decimal dot/comma and a fixed number of decimals! type=float which allows for scientific notation, e.g. 1.2e42
