A similar solution was posted by @Seif_Shebl[here](https://discourse.julialang.org/t/how-to-print-a-number-to-x-digits/50526/2).

To further increase the number of printed digits, say to 100, one can use BigFloats:

```julia
using Printf
Base.show(io::IO, f::BigFloat) = @printf(io, "%.100f", f)

julia> BigFloat(pi)
