如何在 Python 中将数字向上取整?
How does one round a number UP in Python?
我试过 round(number) 但它会将数字向下舍入.示例:
I tried round(number) but it rounds the number down. Example:
round(2.3) = 2.0
而不是 3,如我所愿.
and not 3, as I would like.
我尝试了 int(number + .5) 但它再次将数字四舍五入!示例:
The I tried int(number + .5) but it round the number down again! Example:
int(2.3 + .5) = 2
推荐答案
ceil(天花板)功能:
import math print(int(math.ceil(4.2)))
