I'm sure the precision issue of Decimal.normalize() can be adjusted to what is needed using context settings, but considering the already slow speed and not needing ridiculous precision and the fact that I'd still be converting from a float and losing precision anyway, I didn't think it was worth pursuing. Parameters:arr : 1-D array or sequencetrim : trim is an optional parameter with default value to be fb'(front and back) we can either select f'(front) and b for back. The below article might be a good read: https://docs.python.org/2/tutorial/floatingpoint.html It explains why Python displays floats in the above format. In the above code, a for loop is opened for working, and the list slicing process is done with the help of the startswith() function. The above code provides the following output: In the above code, we use two iteration statements, a for loop and a while loop, the latter being nested within the former. What is this fallacy: Perfection is impossible, therefore imperfection should be overlooked, Allow non-GPL plugins in a GPL main program. Does balls to the wall mean full speed ahead or full speed ahead and nosedive? Me, I'd do ('%f' % x).rstrip('0').rstrip('.') rstrip(), or "right strip", removes a given character from the end of a string if they exist. How to prevent float from removing zero after point? Does the collective noun "parliament of owls" originate in "parliament of fowls"? The proposed solutions do not work when the magnitude of the number is not known in advance, which is common in scientific applications rather than in money-related ones. Updated Generalized to maintain precision and handle unseen values: Copyright 2022 SemicolonWorld. " {:.5g}".format(x) will format x using 5 digits of precision (including before and after the decimal separator), removing trailing zeroes and the decimal dot for integers. This tutorial demonstrates the several ways available to remove leading zeros in a string in Python. It is a side effect of floating numbers not being able to represent the accuracy if more digits are required on the left side. ))0+ (?=\b| [^0-9])') b = rgx.sub ('\2',a) Where b is the result of removing tailing zeros after the decimal point from a. . It doesn't necessarily look like that in the proportional font used for the regular text in the description, but if you copy the test cases to a text editor that uses a fixed width font, like Courier, you'll see there are four spaces between the 12.3 and the 60: one space for each of the three zeros removed and one that was originally there. How do I concatenate two lists in Python? The consent submitted will only be used for data processing originating from this website. python program output with trailing zero.. How to get output with zero. To register a nondeterministic Python function, users need to first build a nondeterministic user-defined function for the Python function and then register it as a SQL function. How does the Chameleon's Arcane/Divine focus interact with magic item crafting? I'm not concerned with the possible "-0" result since -0.0 is a valid floating point number and it would probably be a rare occurrence anyway, but since you did mention you want to keep the string result as short as possible, you could always use an extra conditional at very little extra speed cost. Most of the solutions here (including this one) totally forget about integers ending in 0 which is an unwanted behavior. @CecilCurry perhaps, but you are mistaken.
