A round-to-nearest operation takes an original number with an implicit or specified precision; examines the next digit, which is at that precision plus one; and returns the nearest number with the same precision as the original number. For positive numbers, if the next digit is from 0 throug...
it returns the nearest integer to its input. Delegates to number.__round__(ndigits).For the built-in types supporting round(), values are rounded to the closest multiple of 10 to the power

Since Python 3.0, round() uses banker's rounding where .5 fractions are rounded to the nearest even number:>>> round(0.5) 0 >>> round(1.5) 2 >>> round(2.5) 2 >>> import numpy # numpy does the same >>> numpy.round(0.5) 0.0 >>> numpy.round(1.5) 2.0 >>> numpy.round(2.5)...
"Round down," while similar, is not the same. As the name implies, Round Down reduce a number to the nearest lower integer. For example - Original value Value after Round Down 10.2 10 5.23 5 The above table is an overview of how rounding down values works. You might be wondering,...
