That's not how it (rounding to the closest integer) is defined.

It doesn't exist as a machine Int.

Should this be handled this way?  Or is it better to make round(Int,
typemin(Float64)) to be typemin(Int)?

Also, why is typemin(Float64) -Inf but typemin(Int) -9223372036854775808?
Can typemin(Int) be made -Inf as well?
