The following modification of the collections.Counter implementation
https://hg.python.org/cpython/rev/fe4efc0032b5
was just checked in with the line
result[elem] = 0 - count
Does this have an advantage over the obvious
result[elem] = -count
?
x = 0.0
-x
-0.0
0 - x
0.0
That's a subtle difference, but does it matter in the context of the patch?
I don't know. Perhaps there is more meaningful difference for decimals.
This code is not new (see
https://hg.python.org/cpython/rev/e908ebc160f0).
