4. 使用示例 (Usage Examples) 4.1 四舍五入为整数 (Rounding to the Nearest Integer) print(round(3.6)) # 输出: 4print(round(3.3)) # 输出: 3 在这个示例中,3.6被四舍五入为4,而3.3则被四舍五入为3。 4.2 指定小数位数 (Specifying the Number ofdecimalPlaces) print(round(3.14159, 2)) # 输...
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...
to get it done, we can use an f-string like this: val = 42.1 print(f'{val:.2f}') # for more details have a look at the python docs result is: 42.10 13th Aug 2024, 12:42 PM Lothar + 4 I would not suggest using the round() method to get the nearest integer, it is ...
要查看该round()函数在实际中的工作方式,请考虑以下微型程序: Some numbers to round valueA = 3.14159265359 valueB = 1845.7409947 valueC = -100.95 valueD = 9.5432 valueE = 34.49953 Round values to whole numbers roundA = round(valueA) roundB = round(valueB) ...
use round() 11th Jan 2021, 2:39 PM Steven Wen + 8 keorapetse Moagi , it depends what exactly is mentioned in the task description. When it says: <... rounded up to the nearest whole number>, you should use math.ceil(). this is working like this: from math import ceil a = 5....
1. Divide it by the unit to which it is to be rounded 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 ...

python标准库的解释及翻译round(number[, ndigits])Return the floating point value number rounded to ndigits digits after the decimal point. If ndigits is omitted, it returns the nearest integer to its input. Delegates to number.__round__(ndigits).For the built-in types...
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...
