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
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...

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,...
