Actually this isn’t quite so simple - as the problem outline below compounds
itself by the use of #average (which uses #sum and not #sumNumbers) and thus
gives a less precise answer.
Why wouldn’t #average use #sumNumbers inside? Or does there need to be
#averageNumbers as a complement ….
Actually I can answer my own question - its the difference between #sum and
#sumNumbers (and an easy mistake to make - I almost wish that sum was the
sumNumbers implementation and there was a sumSample that behaved like now)

Hi guys - I recall this came up a few months ago, but I’m curious about the
difference of Pharo’s use of Float64 vs Python - as I assumed that if languages
use the same IEEE spec (or whatever spec it is) that simple stuff would be
quite similar.
I am curious why in Python adding these numbers:
