i made a few amendmends to PHP/Session/Serializer/PHP.pm so that it now
detects scientific notation. At least it works for me. I do know, that
the way i did it is most probably not the best/nicest/most elegant way
(i guess there is some cool way with sprintf to convert values in
scientific notation to a double), but it works for me and i am happy
with it.
maybe this piece of code is for some use for somebody and maybe that re
which i added in @re could be added to the module by the maintainer
'd:(-?\d+(?:\.\d+)?(?:E(?:\-|\+)\d)?);',
# double with scientific notation such as d:1.0E+6
