Sum-safe Rounding for Iterables

iteround's Issues

Deadlock with empty list and non-zero `topline`

Running this line will result in deadlock:

a = 1 # Any number that is not zero
iteround.saferound([], 0, topline=a)

It would be nice if it raises an exception instead.

Reverse order of saferounding

Hi,

I am using saferound for a Pandas DataFrame column. Saferound seems to preferentially "award" the leftover sums to the first item in the array. I would like to reverse this order, "awarding" the leftover to the last item in the array, without reversing the order of the array (which I can't do because it can't be guaranteed that values in the array will always be so similar - they might be very different too - and I have a certain array order I wish to preserve in relation to other columns). Could that be possible?

df["column"] = iteround.saferound(df["column"], 2)

So instead of:

43.34
43.33
43.33

it should be:

43.33
43.33
43.34

It's now on conda!

Just a little notification that a while back I took the liberty of adding iteround on conda-forge. Oppurtunity to add another badge to the README 😉
