[julia-users] Why is typeof hex or binary number Uint64, while typeof decimal number is Int64?

[Phil Tomson]

julia> typeof(-0b111)
Uint64

julia> typeof(-7)
Int64

julia> typeof(-0x7)
Uint64

julia> typeof(-7)
Int64

I find this a bit surprising. Why does the base of the number determine 
signed or unsigned-ness? Is this intentional or possibly a bug?
