fracElement
A mathematical fraction.
Example
$ 1/2 < (x+1)/2 $
$ ((x+1)) / 2 = frac(a, b) $
Syntax
This function also has dedicated syntax: Use a slash to turn neighbouring expressions into a fraction. Multiple atoms can be grouped into a single expression using round grouping parentheses. Such parentheses are removed from the output, but you can nest multiple to force them.
Parameters

denom
The fraction's denominator.

// Grouping parentheses are removed.
#set math.frac(style: "skewed")
$ (a + b) / b $
// Grouping parentheses are retained.
#set math.frac(style: "horizontal")
$ (a + b) / b $
