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.
