Dear all, I find that whether or not use passmissing, the results are the same. So when should we use passmissing?Here are some examples. julia> sqrt(missing) missing julia> passmissing(sqrt)(missing) missing julia> abs.([1, 2, missing]) 3-element Vector{Union{Missing, Int64}}: 1 2 missing …

In the main its for “lifting” functions which don’t have a method to deal with Missing: julia> parse.(Int, ["1", missing, "2"]) ERROR: MethodError: no method matching parse(::Type{Int64}, ::Missing) versus julia> passmissing(parse).(Int, ["1", missing, "2"]) 3-element Vector{Union{Missing, Int64}…

Missing handling is quite inconsistent in Base Julia, even across simple mathematical functions: julia> sin(missing) missing julia> sind(missing) ERROR: MethodError That’s where passmissing or manual checks come in handy.
