Left/Right

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.

To prevent a delimiter from being matched by Typst, and thus auto-scaled, escape it with a backslash. To instead disable auto-scaling completely, use set math.lr(size: 1em).

Example

Scales delimiters.

While matched delimiters scale by default, this can be used to scale unmatched delimiters and to control the delimiter scaling more precisely.

#math.lr(
  size: relative,
  body
) -> content

Parameters

Scales delimiters vertically to the nearest surrounding lr() group.

#math.mid(
  body
) -> content

Parameters

Takes the absolute value of an expression.

#math.abs(
  size: relative,
  body
) -> content

Parameters

Takes the norm of an expression.

#math.norm(
  size: relative,
  body
) -> content

Parameters

Floors an expression.

#math.floor(
  size: relative,
  body
) -> content

Parameters

Ceils an expression.

#math.ceil(
  size: relative,
  body
) -> content

Parameters

Rounds an expression.

#math.round(
  size: relative,
  body
) -> content
