POLL: Math questions regarding upper elementary school (xpost to m.k.)

BEEP! You can't use stem-and-leaf plots with proportional fonts! Mono-space fonts only!!! (Or very difficult tabular typsetting to force each digit to have the same width.) Wow, I didn't know this and it does have an impact on the information I'm trying to gather, so THANK YOU! Alan Rosenthal correctly pointed out to me by e-mail that most proportional fonts use mono-spacing for digits, to make setting tables of numbers easier. In fact, he challenged me to come up with a widely-used font that did NOT have mono-spaced digits. I looked through some font metric tables and only found a few fonts that did not have the same width for both 0 and 1. Several fonts of the Lucida and Lucida Bright families from Y&Y have this problem: yandy/lubright/lbdsc.afm:C 48 ; WX 664 ; N zero ; B 36 -12 628 548 ; yandy/lubright/lbdsc.afm:C 49 ; WX 500 ; N one ; B 69 0 449 542 ; yandy/lubright/lbrsc.afm:C 48 ; WX 639 ; N zero ; B 48 -12 590 542 ; yandy/lubright/lbrsc.afm:C 49 ; WX 494 ; N one ; B 81 0 413 542 ; yandy/lucida/lbc.afm:C 48 ; WX 664 ; N zero ; B 120 -12 651 542 ; yandy/lucida/lbc.afm:C 49 ; WX 434 ; N one ; B 72 0 386 542 ; yandy/lucida/lbl.afm:C 48 ; WX 533 ; N zero ; B 33 -12 500 554 ; yandy/lucida/lbl.afm:C 49 ; WX 451 ; N one ; B 27 -6 427 554 ; yandy/lumath/lbmdtex.afm:C 49 ; WX 623 ; N one ; B 120 0 517 729 ; yandy/lumath/lbmdtex.afm:C 156 ; WX 624 ; N zeroslash ; B 32 -66 592 789 ; which is somehwat surprising, as the Lucida family is one of the few fonts that is designed to work well with the TeX math-typesetting package. There are undoubtedly other fonts with proportional spacing of the digits, but we only have a small collection of font tables on the machine I checked. The most commonly used fonts DO mono-space their digits, even ones with enormous variation in letter widths (like Avant Garde). Note: this topic seems to be drifting out of the proper topic area for mkm. I suggest that we not discuss fonts further on the newsgroup, but (as Alan already wisely did) take any further discussions on fonts to e-mail. -- Kevin Karplus http://www.soe.ucsc.edu/~karplus life member (LAB, Adventure Cycling, American Youth Hostels) Effective Cycling Instructor #218-ck (lapsed) Professor of Computer Engineering, University of California, Santa Cruz Undergraduate and Graduate Director, Bioinformatics Affiliations for identification only. |
