For pd64, I would just remove the precision (.6) and go normal %g, leaving it up to the system. I don't see the need for making it configurable globally or on a per-object basis, which is adding more complexity. Keep the "data pure" so people can clip, filter, apply an epsilon check for small numbers, etc. ;)
If you want to show *everything* losslessly, apparently %.9g for float and %.17g for double, although that seems overdone to me. There are also the FLT_DECIMAL_DIG and DBL_DECIMAL_DIG defines in float.h for this. :) Ref: https://stackoverflow.com/a/21162120 I prefer the simplicity of letting %g of just do it's thing in this case, and keep %.6g as it is for pd32. > On Nov 26, 2024, at 2:20 AM, pd-dev-requ...@lists.iem.at wrote: > > Message: 3 > Date: Mon, 25 Nov 2024 22:20:32 -0300 > From: Alexandre Torres Porres <por...@gmail.com <mailto:por...@gmail.com>> > Subject: [PD-dev] Re: why nor increase the '%g' precision for pd64? > To: Giulio Moro <giuliom...@yahoo.it <mailto:giuliom...@yahoo.it>> > Cc: pd-dev <pd-dev@lists.iem.at <mailto:pd-dev@lists.iem.at>> > Message-ID: > <CAEAsFmg=f9zwi0970c83sp4dmygoof794w-5dbftsvcuy0f...@mail.gmail.com > <mailto:CAEAsFmg=f9zwi0970c83sp4dmygoof794w-5dbftsvcuy0f...@mail.gmail.com>> > Content-Type: multipart/alternative; > boundary="00000000000076eed00627c6a88b" > > The thing is that a higher precision in single precision will give you many > float imprecision errors and it's also annoying. > > I guess using %g is a good compromise for single precision in messages, > objects (as arguments) and comments.
