For example, the number 2.5 rounded to the nearest whole number is 3. The number 1.64 rounded to one decimal place is 1.6.Now open up an interpreter session and round 2.5 to the nearest whole number using Python’s built-in round() function:...
from decimal import Decimal, ROUND_HALF_UP def round(number, ndigits=None): """强制四舍五入""" exp = Decimal('1.{}'.format(ndigits * '0')) if ndigits else Decimal('1') return type(number)(Decimal(number).quantize(exp, ROUND_HALF_UP)) print(round(4.115, 2), type(round(4.115...
round单词本身有四舍五入的意思,up则是向上,表示向上取位, ROUNDUP(number, num_digits) 第一个参数是数值, 第二个是向上取舍的位数,取整数 如果num_digits 大于 0(零),则将数字向上舍入到指定的小数位数。 如果num_digits 为 0,则将数字向上舍入到最接近的整数。 如果num_digits 小于 0,则将数字向上舍...

既然有UP,那么就一定有DOWN ROUNDDOWN函数用法和ROUNDUP函数一样,不相处在于一个是向下,一个是向上 当ROUNDDOWN函数第二个参数为0时,其功能就和INT取整函数相同了 Int( number )将数字向下舍入到最接近的整数,例: 与期相反,CEILING函数是向上取整 CEILING(number, significance),ceiling英文是天花板的意思,函如其名...
Write a Python function to round up a number to specified digits. Sample Solution:Python Code:import math def roundup(a, digits=0): n = 10**-digits return round(math.ceil(a / n) * n, digits) x = 123.01247 print("Original Number: ",x) print(roundup(x, 0)) print(roundup(x, 1...
round(number, ndigits) round() Parameters Theround()function takes two parameters: number- the number to be rounded. ndigits (optional)- number up to which the given number is rounded; defaults to0. round() Return Value Theround()function returns the ...

print("Rounded number using banker's rounding:", rounded_num) 在这个示例中,2.5 四舍五入的结果为 2,而不是 3。 向上或向下舍入 可以使用正负号来控制 ndigits 参数,以指定向上或向下舍入。 num = 10.4 rounded_down = round(num, -1) #向下舍入rounded_up = round(num, 1) #向上舍入print("...
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 = 5.01 b = 5.99 print(ceil(a)) # result is 6 print(ceil...
