Is it possible to get the result of a computation in the form

```julia
2pi//5
2√2//3

```

just like there is for Rationals?

no, you can probably try to delay the calculation yourself

Depending on what are you aiming for, you can take a look at `Symbolics`:

```julia
julia> using Symbolics

julia> @variables pi sq2
2-element Vector{Num}:
  pi
 sq2

julia> formula = 2 * pi // ( 3 * sq2 )
(2pi) / (3sq2)

julia> substitute(formula, Dict(pi => π, sq2 => √2))
1.4809609793861218

```

There is [this package](https://github.com/perrutquist/IrrationalExpressions.jl) which seems to be heavy on the type piracy but if it’s for private use that’s probably fine.

(There’s a pun on the word “privateer” in here somewhere)
