Well, at least for my use I "fixed" it with rstrip('.'), and it would
possibly also work to convert to CDF and then to Integer, though that
would possibly create other hard-to-find problems.
Well, it's worth raising the issue, even if the answer is negative.
I for one never noticed int() didn't take a float string, even though it
takes an int string or a float.
