[julia-users] printing UInt displays hex instead of decimal

[holocronweaver]

In Julia 0.4rc1, when I create a UInt, either as an individual value or 
array, and then print it hex values are usually displayed instead of 
decimals. I say 'usually' because the behavior changes a bit between REPL 
and 

For instance:

julia> a = UInt[1 2 3 4]
1x4 Array{UInt64,2}:
 0x0000000000000001  0x0000000000000002  …  0x0000000000000004

This annoys me because 98% of the time I want the decimal representation. 
Decimal is shown for Int, so why is hex the default for UInt? Is it a bug?
