Use the `round()` function to round a number to the nearest 100, e.g. `result = round(num, -2)`.
方法一:使用数学模块math中的ceil和floor函数 Python的math模块中提供了ceil和floor函数,分别用于向上取整和向下取整。我们可以利用这两个函数来实现对一个数按照5的倍数取整的操作。 importmathdefround_to_nearest_multiple_of_5(number):return5*round(number/5) 1. 2. 3. 4. 方法二:使用整除运算符// 另一...
self.assertEqual(s.roundToNearest(GiB, rounding=size.ROUND_UP), Size("11 GiB"))# >>> Size("10.3 GiB").convertTo(MiB)# Decimal('10547.19999980926513671875')self.assertEqual(s.roundToNearest(MiB), Size("10547 MiB")) self.assertEqual(s.roundToNearest(MiB, rounding=size.ROUND_UP), Size(...
2. Round it to the nearest whole number, unless it ends in exactly .5 3. If it ends in exactly .5, then round towards the nearestevenwhole number 4. Multiply it by the unit to which it is to be rounded Examples(rounded to hundredths): 3.0448 → 304.48 → 304 → 3.04 3.0450 → 3...
I would not suggest using the round() method to get the nearest integer, it is because the round() method uses banker's rounds, which can give an expected (for normal use) result. For example: round(2.5) # 2 round(2.5, 0) # 2.0 This post has info about that issue. To get the...

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...
