Using “old-style” figures

+

These numbers are also called medieval or lowercase figures and their +use is mostly font-specific. Terminology is confusing since the +lining figures (which are now the default) are a relatively recent +development (19th century) and before they arrived, oldstyle figures +were the norm, even when setting mathematics. (An example is Thomas +Harriot’s Artis Analyticae Praxis published in 1631). In a +typical old style 3, 4, 5, 7 and 9 have descenders and 6 and 8 ascend +above the x-height; sometimes 2 will also ascend (this last seems to +be a variation associated with French typography). +

LaTeX provides a command \oldstylenums{digits}, which +by default uses an old-style set embedded in Knuth’s ‘math italic’ +font. The command isn’t sensitive to the font style of surrounding +text: the glyphs are only available to match the normal medium weight +Computer Modern Roman fonts. +

The textcomp package changes \oldstylenums to use the +glyphs in the Text Companion fonts (LaTeX TS1 encoding) when +in text mode, and also makes them available using the macros of the +form \text<number>oldstyle, e.g., \textzerooldstyle. +(Of course, not all font families can provide this facility.) +

Some font packages (e.g., mathpazo) make old-style figures +available and provide explicit support for making them the default: +\usepackage[osf]{mathpazo} selects a form where digits are +always old-style in text. The fontinst package will +automatically generate “old-style versions” of commercial Adobe Type +1 font families for which “expert” sets are available. +

It’s also possible to make virtual fonts, that offer old-style digits, +from existing font packages. The cmolddig bundle provides +a such a virtual version of Knuth’s originals, and the eco +or hfoldsty bundles both provide versions of the EC +fonts. The lm family offers old-style figures to OpenType +users (see below), but we have no stable mapping for lm +with old-style digits from the Adobe Type 1 versions of the fonts. +

Originally, oldstyle figures were only to be found the expert sets of +commercial fonts, but now they are increasingly widely available. An +example is Matthew Carter’s Georgia font, which has old-style figures +as its normal form (the font was created for inclusion with certain +Microsoft products and is intended for on-screen viewing). +

OpenType fonts have a pair of axes for number variations — +proportional/tabular and lining/oldstyle selections are commonly +available. “Full feature access” to OpenType fonts, making such +options available to the (La)TeX user, is already supported by +XeTeX using, for example, the fontspec +package. Similar support is also in the works for +LuaTeX. +
