Dear All, I have a new tipometer now, and I wondered, that by Rotring Didot-point is no more 0,376 but 0,375 mm. Actually the new Didot-size is more komfortable, because one Cicero is exactly equal to 4,5 mm, two Cicero to 9 mm. I have attached a small patch, which introduces two new units: nd (new didot) and nc (new cicero). Maybe we have to follow the sounds of new times. Any comments? Greetings, Bence -- Nagy Bence | Tipográl.hu

I happily support any unit that uses a unique two letter identifier (there is already a "px" in pdfxtex: 96px=1in). Taco

nd and nc sound ok to me (btw, what happened to the 10% (% being letter)) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Interesting! Found a reference to this also in Forssmann's "Lesetypographie" on p. 81 (new Didot point has been standardized in 1978). It seems that the quotient 1238/1160 can still be improved, see the q&d awk program: BEGIN{ for (i=1;i<5000;i++){ j=i*25.4/72.27/0.375 jj = int(j+0.5); x = jj - j; n = i*25.4/72.27/jj printf("%4d %4d %14.8f %14.8f\n", i,jj,n,x) if(x<0) x*=-1 if (x<0.0001) print "=====================" } } which tells 685/642 --> 0.37499995mm Regards, Hartmut

ah, that makes the current implementation a bug -) btw, similar rounding situations occur with A values: 4*width(A7) <> height(A4) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

ooops, it was the "Detailtypografie" (Forssmann and de Jong).
1978).

:-) interesting that Knuth still chose the old definition
btw, similar rounding situations occur with A values:
4*width(A7) <> height(A4)
this one isn't caused by TeX; it's defined by the ISO standard, which tells to calculate A1, A2,... by repeated division from A0, and after each division one has to round to the next lower integer (floor). So all these A* dimensions do _not_ fit together already by the standard (which is IMHO a pity; one can't put a nice sqrt(2) formula on the whiteboard telling that A* paper sizes are strictly following this beautiful principle).

Dear Hartmut,
Interesting! Found a reference to this also in Forssmann's "Lesetypographie" on p. 81 (new Didot point has been standardized in 1978).
I never heard about this unit before I got the new typometer. There is no one hungarian book about typography (written after 1990), which contains information about the new Didot-point.
which tells 685/642 --> 0.37499995mm
Nice work! Don't you mean, it can be introduced with your quotient in the next release? Greetings, Bence -- Nagy Bence | Tipográl.hu
