Hmmm... let me check something:
###
>>> '%0.1f' % 0.66
'0.7'
>>> '%0.2f' % 0.66
'0.66'
###
The rounding behavior of format strings might account for the discrepency
in the space-time continuum. As you've notice, int() doesn't round, but
instead truncates --- it just drops the fractional part of a float on the
ground:
###
>>> int(-4.5)
-4
>>> int(4.5)
4
###
You might want to use a round() in the expression:
> rev= int((minor-minor_ver)*10**6)
###
rev = int(round((minor-minor_ver)*10**6))
###
and thereby repair the singularity.
Good luck!
