I've been looking at this recently with v4.0 and it seems it would be rather
awkward. I haven't delved too deeply yet, but typedef Number is used for
both floating and integer values in struct Value - and a 32-bit float cannot
accurately represent a 32-bit int! What you may be seeing is "collisions"
between nearby integer values.

Having everything as double will be affecting performance as well as
footprint: on the PS2, one of the platforms I'm working with, double
precision has to be emulated in software.
