round() doesn't seem to be rounding properly
I can't help the way it's stored, but at least formatting works correctly:
'%.1f' % round(n, 1) # Gives you '5.6'
If you use the Decimal module you can approximate without the use of the 'round' function. Here is what I've been using for rounding especially when writing monetary applications:
from decimal import Decimal, ROUND_UPDecimal(str(16.2)).quantize(Decimal('.01'), rounding=ROUND_UP)This will return a Decimal Number which is 16.20.
