You are quite right, probably a wrong hypothesis on my part, albeit looking at the values in the data sample supplied in the OP, many come pretty close to the 32-bit signed integer limit, leading to think that the others might just be above it. Actually, thinking again about it, it seems to me that Perl itself (and, I guess pure Perl modules) can handle larger integers (or possibly I am lucky enough to use only 64-bits integers on the platforms I have been using in the recent years). But I have encountered the problem in the past with some modules and I am almost sure that I have also encountered the NaN thing with integers with some of them. It is too long ago for me to remember the details, though, I may confuse different issues. Anyway, we don't know enough about the OP's program to make this type of hypotheses.
