in thread Negative zero from a multiplication by a zero?

Not all machines and libraries support negative zeroes. Perl lets the underlying layers handle this, so the results won't be the same on all machines.

    I think all the posts here are on the same track...HUGE negative or positive values can yield unpredictable results.

      eh? The results are predictable and intentional (on a platform with support for negative zeroes), and they exist to support small values.

        When I said, results can be unpredictable...that meant that source code on machine X may not generate the same results as on machine Y. Machine X will probably do what Machine X does repeatably!

        I think the whole idea of this thread was that when you are dealing with either very big or very small numbers, there are a lot of ways to "get into trouble", meaning that numeric results for the same source just may not be equal.
