I'd like to mention that there's no such mathematical object as 
"uniform distribution on [0..+infinity)".  On the other hand, a 
(discrete) uniform distribution of the bit pattern, or restricted 
bit pattern (that is, no special values), is of course valid.  A 
"random positive double" as a bit pattern most closely resembles 
exponential distribution I think.
