Serhat, not sure where you are looking at but with Server Data Formatter we have over 70 data formats for quite a while now and Round has always being there.

George realy Thank you for your guide … I have been expecting this response for a long time and the project has stopped because of this reason. I can continue now.

I am confused by this @George. I want to do a division calculation and round the result to 2 decimal places but end up with a number that I can then use in other calculations.

According to Wappler, the Format Number function will leave me with a string which potentially has a delimiter too.

How can I do a round to 2 decimal places and end up with a number? Do I then have to do a .toNumber() on the result? Or is there a .round(2) function somewhere that I can use?

Second Question...

I have just tried to do the above using the experimental mode user interface and I have ended up with this syntax:

Hello Antony,
It doesn’t matter if it’s on the server side or on the client side - when making calculations and want to use the numbers formatting options on a value which is not a number then you first need to convert it to number.
So (value1.tonumber + value2.tonumber).some_other_formatter
