确保变量可被4整除 [英] Ensure a variable is divisible by 4

问题描述

我确信这是一个基本的数学问题，但有没有更好的方法来确保一个int变量可以被4整除，而不是通过执行以下操作来获得;


x = 111

x =（x / 4）* 4


对我来说似乎有点笨拙。

I am sure this is a basic math issue, but is there a better way to
ensure an int variable is divisible by 4 than by doing the following;

x = 111
x = (x /4) * 4

Just seems a bit clunky to me.

Division with rest:

>> x％4

>>x % 4

使用模运算符''％''


如果不是x％4：

＃

＃如果x是模4可分，则到达这里

-Larry Bates

Use modulo operator ''%''

if not x % 4:
#
# Arrive here if x is modulo 4 divisable

如果x％4 == 0：

＃x可以整除4

if x % 4 == 0:
# x is divisible by 4
