drop trailing zeros from decimal

I have a long list of Decimals and that I have to adjust by factors of 10, 100, 1000,..... 1000000 depending on certain conditions. When I multiply them there is sometimes a useless trailing zero (though not always) that I want to get rid of. For example... from decimal import Decimal # outputs 25.0, PROBLEM! I would like it to output 25 print Decimal('2.5') * 10 # outputs 2567.8000, PROBLEM! I would like it to output 2567.8 print Decimal('2.5678') * 1000 Is there a function that tells the decimal object to drop these insignificant zeros? The only way I can think of doing this is to convert to a string and replace them using regular expressions. Should probably mention that I am using python 2.6.5 EDIT senderle's fine answer made me realize that I occasionally get a number like 250.0 which when normalized produces 2.5E+2. I guess in these cases I could try to sort them out and convert to a int
There's probably a better way of doing this, but you could use .rstrip('0').rstrip('.') to achieve the result that you want. Using your numbers as an example: >>> s = str(Decimal('2.5') * 10) >>> print s.rstrip('0').rstrip('.') if '.' in s else s 25 >>> s = str(Decimal('2.5678') * 1000) >>> print s.rstrip('0').rstrip('.') if '.' in s else s 2567.8 And here's the fix for the problem that @gerrit pointed out in the comments: >>> s = str(Decimal('1500')) >>> print s.rstrip('0').rstrip('.') if '.' in s else s 1500
