But typemax(Float64) gives 'Inf' which is probably not what the author wanted. The trick is to use prevfloat(typemax(Float64)) which is not that obvious.

julia> typemax(Float64)
Inf
julia> prevfloat(typemax(Float64))

For questions like this, you will be best served by looking at the julia docs https://docs.julialang.org/en/v1/base/base/#Base.typemin

Specifically for this question, typemin(Int), and typemax(Int) should do what you want.
