Before rebasing, I think that there are a few small problems with the
modification applied to switch from an integer range to double.
(1) ISTM that the + 0.5 which remains in the PoissonRand computation comes
from the previous integer approach and is not needed here. If I'm not
mistaken the formula should be plain:
-log(uniform) * center
(2) I'm not sure of the name "center", I think that "lambda" or "mean" would be more appropriate.
(3) I wish that the maximum implied multiplier could be explicitely documented in the source code. From pg_rand48
sourcecode, I think that it is 33.27106466687737
