RE: Stem.note-collision-threshold

[Robert Mengual]

Hi Jean, thanks for your reply.

Find attached a tiny example of what I am doing. As you will see, if the interval is composed of 3 semitones (either C D# or C Eb) the noteheads are positioned one of top of the other. However, when the interval is composed of 2 semitones they overlap.

I understand float numbers are tedious, but I don't think there is need for much precision here. I mean, in my case even though I want 2/3 distance between notes I could specify 0.7 and everything should work.

Robert

Comparing floats is hazardous due to decimal precision issues. On the
other hand, it might be possible to make it accept rational numbers like
#3/2.

Could you give a code example? It's not clear to me what different
coordinate systems are being used.

Thanks,
