[julia-users] How fast reduce the Vector range of values? (Recode for smaler numbers)

[paul analyst]

I have a long vector J, which has little value. Unfortunately, these values 
are very different (small and large) J = [1 3 7 2 12548745 2 
125485458544363456345 125485458544363456345 ... 3 12,548,545,854].
The following is a very slow like:
julia> J
1846623-element Array{Int64,1}:
        930070
       1475172
   21474836496435345
   21474836496435345    
4296445417
       641
       130
       130
       143
...
    4296444827
       143
       148
       144
       145

J1=zeros(J)
suJ=sort(unique(J))
l=length(suJ)

for i =1:l
temp=findin(J,[suJ[i]])
J1[temp]=i;if mod(i,1000).==0 println(i) end;
end;
