In my request I wrote:

I meant that each single floating point value is formatted independently with
3.2f. This means my POV was different from the one you have assumed.

I don't know what's the best solution for this, but I think my request is
simpler, just format the two values separately, this means calling and re-using
the usual floating point formatting logic two times.
