# This is responsible for the fact that certain math functions are grouped
# together into one documentation page although they are not part of any scope.
- name: variants
display: Variants
category: math
functions: ["serif", "sans", "frak", "mono", "bb", "cal"]
description: |
Alternate typefaces within formulas.
These functions are distinct from the [`text`]($text) function because math
fonts contain multiple variants of each letter.
- name: styles
display: Styles
category: math
functions: ["upright", "italic", "bold"]
description: |
Alternate letterforms within formulas.
These functions are distinct from the [`text`]($text) function because math
fonts contain multiple variants of each letter.
- name: sizes
display: Sizes
category: math
functions: ["display", "inline", "script", "sscript"]
description: |
Forced size styles for expressions within formulas.
These functions allow manual configuration of the size of equation elements
to make them look as in a display/inline equation or as if used in a root or
sub/superscripts.
- name: underover
display: Under/Over
category: math
functions: [
"underline",
"overline",
"underbrace",
"overbrace",
"underbracket",
"overbracket",
]
description: |
Delimiters above or below parts of an equation.
The braces and brackets further allow you to add an optional annotation
below or above themselves.
- name: roots
display: Roots
category: math
functions: ["root", "sqrt"]
description: |
Square and non-square roots.
# Example
```example
$ sqrt(3 - 2 sqrt(2)) = sqrt(2) - 1 $
$ root(3, x) $
```
- name: attach
display: Attach
category: math
functions: ["attach", "scripts", "limits"]
description: |
Subscript, superscripts, and limits.
Attachments can be displayed either as sub/superscripts, or limits. Typst
automatically decides which is more suitable depending on the base, but you
can also control this manually with the `scripts` and `limits` functions.
# Example
```example
$ sum_(i=0)^n a_i = 2^(1+i) $
```
# Syntax
This function also has dedicated syntax for attachments after the base: Use
the underscore (`_`) to indicate a subscript i.e. bottom attachment and the
hat (`^`) to indicate a superscript i.e. top attachment.
- name: lr
display: Left/Right
category: math
functions: ["lr", "abs", "norm", "floor", "ceil", "round"]
description: |
Delimiter matching.
The `lr` function allows you to match two delimiters and scale them with the
content they contain. While this also happens automatically for delimiters
that match syntactically, `lr` allows you to match two arbitrary delimiters
and control their size exactly. Apart from the `lr` function, Typst provides
a few more functions that create delimiter pairings for absolute, ceiled,
and floored values as well as norms.
# Example
```example
$ [a, b/2] $
$ lr(]sum_(x=1)^n] x, size: #50%) $
$ abs((x + y) / 2) $
```
- name: calc
display: Calculation
category: foundations
path: ["calc"]
description: |
Calculations and processing of numeric values.
These functions are part of the `calc` module and not imported by default.
In addition to the functions listed below, the `calc` module also defines
the constants `pi`, `tau`, `e`, `inf`, and `nan`.
