Of all the methods that you’ve explored in this article, the rounding half to even strategy minimizes rounding bias the best. Fortunately, Python, NumPy, and pandas all default to this strategy, so by using the built-in rounding functions, you’re already well protected!Conclusion...
The documentation for the built-in round() function says that it rounds to the nearest value, rounding ties away from zero. Since the decimal fraction 2.675 is exactly halfway between 2.67 and 2.68, you might expect the result here to be (a binary approximation to) 2.68. It’s not, beca...
Python uses "round half to even" (bankers rounding) which minimizes bias in statistical operations. This example demonstrates the behavior. bankers_rounding.py print(round(2.5)) # 2 (rounds to even) print(round(3.5)) # 4 (rounds to even) print(round(4.5)) # 4 (rounds to even) print(...

The number in program can be rounded to 13.48 or 13.49. By default, theround(...)function rounds down. This can be changed as well: import decimal #Can be rounded to 13.48 or 13.49 rounded = round(13.485, 2) print(decimal.Decimal(rounded).quantize(decimal.Decimal('0.00'), rounding=deci...
def newround(number, ndigits=None): """ See Python 3 documentation: uses Banker's Rounding. Delegates to the __round__ method if for some reason this exists. If not, rounds a number to a given precision in decimal digits (default 0 digits). This returns an int when called with one...
