[R] Random real numbers

[Carl Witthoft]

Well, to be mathematically correct, you cannot choose random real 
numbers for the simple reason that we don't even have names for all the 
reals.
As all of you know (I hope :-) ), there are the same number (aleph-1) of 
reals in any length line segment you wish.  Aside from the unlikelihood 
that you could write a random number generator that produced, say, 
(3.14159^5.432- .3289^3.19847)^(0.274) ,  there are a whole pile of 
transcendentals that you'll never get.


So as always, settle for a random rational number amongst the 2^N values 
your floating point processor can actually produce.
