[julia-users] Re: Quick method to give a random lattice vector that on average points in a particular direction?

[DumpsterDoofus]

Oh, apologies, I forgot to convert the `sign` to Int64. Changing the line 
in question to 

return (int(sign(x))*(rand() < abs(x)), int(sign(y))*(rand() < abs(y)))

In any case, the original question still stands: could this be improved?
