Widgets - configure decimal places

Hi all,

I would need a hint how i can set the decimal places within a widget.

title: =items.Netatmo_Innen_Temp.state is now showing 23.7899948484745534 °C

I added the metadata state description to the item: %.2f °C but this only affects the sitemap.
Thank you

I have changed from Cell to Label Cell. All fine now.
