In PoPyMoodule.c at line 93 or thereabouts, you should see
case POPY_NUMERIC.  Cut and paste this from here to line
132 or so.  That is, you want to move POPY_NUMERIC from being
one of the cases that falls into res = PyInt_FromLong(...
to being one of cases that falls into PyFloat_FromDouble(...

Recompile.   It will then work.  Note:  python2.1 and python2.2
exhibit different behavior than python1.5.  In python1.5, if you
had 2.10 stored, the result would be displayed as 2.1.  In the 2.x
family it will be displayed as something like 2.100000001.  Make sure
you pass it through your own formatting routine before displaying.
