Units with parantheses in fractions don't render as expected

[Netzwerk2]

When writing units with a fraction as the exponent the unit is rendered incorrectly.
The following minimal example demonstrates this behaviour

#import "@preview/zero:0.6.1": zi

#let J-kg-K = zi.declare("J / (kg K)")
#let K-1-2 = zi.declare("K^(1/2)")

$
  #J-kg-K() \ 
  #K-1-2(fraction: "inline") \
  #K-1-2(fraction: "fraction") \
  #K-1-2(fraction: "power")
$

While this can be circumvented with multiple slashes for normal units ("J / kg / K") the same is not possible for units which have fractions as exponents.

Hi @Netzwerk2 ,

grouping with parentheses is not supported. Instead use multiple /, just like you did. This even requires less typing then needed with parentheses.

As for roots of units, decimal notation is supported, e.g. K^0.5. I think this might not yet be documented though.

Thanks for the quick answer!

I tried using K^0.5, however disabling the use-sqrt flag does not always work in the inline fraction mode

#import "@preview/zero:0.6.1": zi

#let K-1-2 = zi.declare("K^-0.5")
#let kg-K1-2 = zi.declare("K^0.5")

$
  #K-1-2(use-sqrt: false) \
  #K-1-2(use-sqrt: false, fraction: "inline") \
  #K-1-2(use-sqrt: false)[42] \
  #K-1-2(use-sqrt: false, fraction: "inline")[42]
$

$
  #kg-K1-2(use-sqrt: false) \
  #kg-K1-2(use-sqrt: false, fraction: "inline") \
  #kg-K1-2(use-sqrt: false)[42] \
  #kg-K1-2(use-sqrt: false, fraction: "inline")[42]
$

Apart from that something like K^(1/3) can't really be done with decimal notation (I personally don't need 1/3, but there might be some cases where one would want to do that).

Good catch! I'll fix that.

About that: irrational units are extremely rare as they are and I'm only aware of the square root case (it makes sense, where would a root of a unit come from, physically?). If you or someone finds an actual usecase, let's talk about it. Otherwise, I think it's unnecessary to support that.

Sounds reasonable. I personally prefer the look of K^(1/2) over K^0.5, but I can totally understand that you don't want to implement this for such a niche case :)
