Precision is controlled by :compact, not :limit.

tpapp commented 4 years ago

That's a fair point, but I am puzzled because I would expect that arrays and vectors would print the same.

julia> show(IOContext(stdout, :limit => false, :compact => true), fill(Float64(π), 3, 3))
[3.14159 3.14159 3.14159; 3.14159 3.14159 3.14159; 3.14159 3.14159 3.14159]
julia> show(IOContext(stdout, :limit => false, :compact => true), fill(Float64(π), 3))
[3.14159, 3.14159, 3.14159]
