In Number field not able to use (.) 'dot'

Hello, community..!
I am using SharePoint online form, in the list I have one column with 'Number' data type.
My problem is i can not use (.) dot in field. And strange is that I can use dot from right-hand side of the keyboard as shown in below, but it converts to the (,) comma.


i can not use dot as shown in below image.


Can anyone know why this happens?

after use right-hand side dot, it converts automatically in comma by itself.

is this is plumsail form behaviour or problem from my end?

Thanks in Advance...!

Hello @harshp924,

The decimal separator depends on the site regional settings.

As I see, your site language is German and its decimal separator is comma (,). That is why the dot is not accepted by number field.
