Shortest identical decimal representation

Question

drop trailing zeros from decimal

How do I get the shortest representation of a Decimal that compares equal?

For example:

Currently, I have my own implementation which first converts to a string, with

if chanstr.endswith('0'):
    chanstr = chanstr[:chanstr.rfind('.')]

which works fine and is only 2 LOC; but is there a better way to write this?

Closed as duplicate because I discovered the other question only after writing this one, but this one is still a useful path for future people. — gerrit, Nov 19 '12 at 17:13

You can use the normalize method to achieve this:

In [112]: print(decimal.Decimal("89.00").normalize())
89
