	No, but I think I see where the confusion comes from. You were thinking
of the values returned by the Noise function (which are something like
-0.01 to 1.01 and are truncated in the way you said) and the values
where Noise can be computed (must be bigger than -10000, and I don't
know the upper limit but there's one). In this case the only solution is
to take advantage of the periodicity of Noise and to bring the values
inside the acceptable range using a modulus (or something similar).
