If you were calculating and storing 1-probability, then seeing a value
of exactly zero would indicate a problem.  But when calculating a number
near 1 using double, you don't have that many decimal digits, no more
than 15 or so.  If 1-probability is 10^-20, then probability calculates
to exactly 1.
