In substance + this package is a poor man solution to the task of typesetting + math fulfilling the ISO regulations "for physical sciences and + technology" (formerly regulations ISO 31/XI, now ISO\,80000). + These regulations refer mostly to the family, series and shape + of fonts to be used with symbols of various nature. + +This package gets inspiration from the ISOmath package by Günter + Milde, but tries to get the same results without using any math + [font] groups (or families). As pdfLaTeX users may recall, this + typesetting program may see at maximum 16 math [font] groups (or + math font families); sometimes this number results in an error + that forbids the user to use the symbols s/he needs. + +The trick used in this package consists in employing text fonts + within the \text command (defined by the amsmath package that, + therefore, is a dependence to which pm-isomath is subjected) and + chose text font families, series, and shapes to be used within + that command argument. + +The commands are such as to fulfil some math requirements; for + example while in the scope of the \boldmath declaration, the + series is automatically set to bold without any user intervention. + The font size is automatically taken care by \text, so that fonts + have the correct size also while typesetting exponents or subscripts. + +Nevertheless, through proper advanced command options, the user + remains the person principally responsible of using the right + font for the right symbol in a document that must fulfil the + ISO regulations. + +This package is usable only with pdfLaTeX; LuaLaTeX and XeLaTeX + can access OpenType math fonts through the package unicode-math, + and with the "math-style=ISO" option they have the math switching + commands agree with the ISO regulations. + +pdfLATeX users have available some packages to fulfil the ISO + requirements; principally the ISOmath package that is subject + to a number of limitations due the the particular math environment + of the user, and libertinust1math that produces a complete set-up + with math fonts that match very well text fonts that are darker + than the standard default Computer Modern ones (including the + CM-super and the Latin Modern ones). + +This package works very well with the Latin Modern fonts; in + practice in math mode it uses the same Latin text fonts, and + the corresponding families, series, and shapes of the LGR + encoded CBfonts; it may work also with the CM and the CM-super + fonts, but the original author never uses them, therefore he + cannot guarantee any suitable result. + +For installation of this package, simply run the pm-isomath.dtx + through pdfLaTeX (and only pdfLaTeX); move the produced sty file + to the .../tex/latex/pm-isomath/ folder; if it does not exist, + create it; similarly move pm-isomath.dtx to .../source/latex/pm-isomath/ + and pm-isomath.pdf to .../doc/latex/pm-isomath/. + + + |
