How to output number with fixed decimals and with comma instead of period?

I am outputing some numbers that needs to be rounded to the first decimal. I am using:

 round(num*10)/10;

which gives me 1, 1.1, 1.2 ...

I need to print the 1 also as 1.0.

Is there an elegant way to do this with CindyJS? In JS it is tofixed().

Furthermore, is there a way to output `4,1` instead of `4.1`?

In my opinion, the nicest would be to have a modifier for the format command (https://cindyjs.org/ref/String_Operators.html#format$2) that just does this.

As a workaround, you could build your own format function similar to the function fmt in https://cindyjs.org/examples/81_Clock.html

When is the implementation planned? It would be great to have x,y already in production mode 😃 For now it’s still period which might confuse some young students that got used to comma in school.
