binomial(-1.0,2) == 1.0
binomial(-1,2) == 0
do we need 2 diferent names? I think the second form is also needed

Another evil example:

It seems that the plot algorithm is somehow deficient in those cases.
In both cases, it's plotting points

Therefore (if I am right) there needs to be a planned procedure for
completing the ReSTification of Sage. For a start, is there anywhere
a list showing which files have not yet been converted?
You can generate such a list
