Round to nearest Fields: AwayFromZero ToEven 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 nu...
一般的四舍五入操作都是使用内置的round方法 In [14]: round(2.675,2) Out[14]: 2.67 文档中这样解释的 The documentation for the built-inround()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...
def myround(x, base=5): return base * round(float(x) / base) 这使我们可以使用非整数的基数,如.25或任何其他分数基数。 我意识到我迟到了,但似乎没有提到这个解决scheme: >>> from __future__ import division # This is only needed on Python 2 >>> def round_to_nearest(n, m): r = n...
