Hi @Karol,
The good news: we do support floating-point values. If your database table number field is setup with “Decimal places”, the application builder can create and update rows properly. My “1.5” gets inserted as “1.5”.
The bad news: if you change the number field’s “Thousand and decimal separator” so that you can use “1,5”, there is indeed an issue inserting that value.
I’ll open a ticket for someone in our team to investigate this for you.
Cheers,
Peter Evans
