A bad example, no doubt.  But the current world population, though
unquestionably an integer, is not exactly known, and it is quite plausible
to say that it is 64########.

Rather than making ill-conceived suggestions for improvement based on
uninformed guesses about established conventions in a field of study with
which familiarity is limited, it is sometimes better to stick to merely
observing the usage and listening to the explanations offered, inserting
only questions as needed to fill in gaps in understanding. --Peter Constable
