[FFmpeg-user] Float formatting in drawtext

[Wolfgang Hugemann]

Hey,

seems to be an easy question, but I have been searching for the answer 
quite a while without success:

If I perform a float calculation via
    text=%{expr\:whatever}
is there any way to format the output the printf way?

I know, the result could be converted to integer and be formatted via
    text=%{eif\:whatever\:d}
but this is restricted to integer results.
