html5 input type text with regex for pattern in mobile

Question

Hi so I'm trying to get a pattern for an input type text that shows numbers and a dot. Going over the apple documentation I see that one can use basically regex to pull only numbers in the keyboard. Something like

<input type="text" pattern="[0-9]*"></input>

I'm looking for a way to have exactly this but also a dot in the keyboard. Any ideas are much appreciated.

Thanks

Answer 1

Just include a dot in the character class.

[0-9.]*

Note that this is also "zero or more digits and dots."
