It looks like you're doing everything properly to me.
There may be some issues with the original vertex values, rounding, etc that
make the numbers you are getting slightly different when doing it POV-Ray vs
another computer language.

I know that under the hood certain numbers are represented as doubles rather
than longs, etc.

But you're doing it the right way.  It's certainly the way I learned how to do
it.
