Sounds like a bug.

Computers generally round decimals (one of the things that ECMAScript 4
will give is true decimal arithmetic). This means that, for example,
javascript:alert(0.1 + 0.2); will actually give you 0.30000000000000004 -
the length of your decimal will determine whether you run into these
errors, so you might or might not be seeing that as the problem. (I don't
know what Firefox uses internally, but you can pretty much bet it will be
a floating point number of some kind - i.e. a fixed number of "safe"
significant figures...)
