定界符匹配。
lr函数允许您匹配两个定界符并按其包含的内容缩放它们。虽然在语法上匹配的定界符也会自动进行，但lr允许您匹配两个任意的定界符并精确控制它们的大小。除了lr函数外，Typst还提供了一些创建绝对值、上取整和下取整值以及范数的定界符配对的其他函数。 [⚠️]
示例
$ [a, b/2] $
$ lr(]sum_(x=1)^n], size: #50%) x $
$ abs((x + y) / 2) $
$ \{ (x / y) \} $
#set math.lr(size: 1em)
$ { (a / b), a, b in (0; 1/2] } $
函数
lr元素自始可用
Scales delimiters.
While matched delimiters scale by default, this can be used to scale unmatched delimiters and to control the delimiter scaling more precisely.
size默认值：100% + 0pt
The size of the brackets, relative to the height of the wrapped content.
body
The delimited content, including the delimiters.
mid元素0.10.0起可用
Scales delimiters vertically to the nearest surrounding lr() group.
展开示例
$ { x mid(|) sum_(i=1)^n w_i abs(f_i (x)) < 1 } $
body
The content to be scaled.
abs自始可用
Takes the absolute value of an expression.
展开示例
$ abs(x/2) $
size
The size of the brackets, relative to the height of the wrapped content.
Default: The current value of lr.size.
body
The expression to take the absolute value of.
norm自始可用
Takes the norm of an expression.
展开示例
$ norm(x/2) $
size
The size of the brackets, relative to the height of the wrapped content.
Default: The current value of lr.size.
body
The expression to take the norm of.
floor自始可用
Floors an expression.
展开示例
$ floor(x/2) $
size
The size of the brackets, relative to the height of the wrapped content.
Default: The current value of lr.size.
body
The expression to floor.
ceil自始可用
Ceils an expression.
展开示例
$ ceil(x/2) $
size
The size of the brackets, relative to the height of the wrapped content.
Default: The current value of lr.size.
body
The expression to ceil.
round自始可用
Rounds an expression.
展开示例
$ round(x/2) $
size
The size of the brackets, relative to the height of the wrapped content.
Default: The current value of lr.size.
body
The expression to round.
