--- Comment #6 from Damjan Jovanovic damjan.jov@gmail.com 2009-05-15 03:11:37 --- Another patch that strips the trailing decimal zeroes when rounding has been accepted into git last night.
The only real problem I still see is that 0.099 + #.## is rounded to 0.09 instead of 0.1 - and I think I can fix that too.
