There seem to be some longstanding bugs in the floating-point formatting provided by the Formatting.jl package (e.g. [printfmt("1:.4e, 40000.0) prints 3.10000e+04 · Issue #71 · JuliaIO/Formatting.jl · GitHub](https://github.com/JuliaIO/Formatting.jl/issues/71)).

I would tend to recommend using Julia’s [`Printf` standard library](https://docs.julialang.org/en/v1/stdlib/Printf/) instead:

```nohighlight
julia> using Printf

julia> @sprintf("%0.4E", 3.0e-8)
"3.0000E-08"

```
