Variants
Alternate typefaces within formulas.
These functions are distinct from the text function because math fonts contain multiple variants of each letter.
Functions
serif
Serif (roman) font style in math.
This is already the default.
body
The content to style.
sans
Sans-serif font style in math.
$ sans(A B C) $
body
The content to style.
frak
Fraktur font style in math.
$ frak(P) $
body
The content to style.
mono
Monospace font style in math.
$ mono(x + y = z) $
body
The content to style.
bb
Blackboard bold (double-struck) font style in math.
For uppercase latin letters, blackboard bold is additionally available through symbols of the form NN and RR.
$ bb(b) $
$ bb(N) = NN $
$ f: NN -> RR $
body
The content to style.
cal
Calligraphic font style in math.
Let $cal(P)$ be the set of ...
This corresponds both to LaTeX's \mathcal and \mathscr as both of these styles share the same Unicode codepoints. Switching between the styles is thus only possible if supported by the font via font features.
For the default math font, the roundhand style is available through the ss01 feature. Therefore, you could define your own version of \mathscr like this:
#let scr(it) = text(
features: ("ss01",),
box($cal(it)$),
)
We establish $cal(P) != scr(P)$.
(The box is not conceptually necessary, but unfortunately currently needed due to limitations in Typst's text style handling in math.)
body
The content to style.
