浮在地板上 [英] Taking the floor of a float

问题描述

我发现了两种使用Python发言的方法:

I have found two ways of taking floors in Python:

3.1415 // 1

和

import math
math.floor(3.1415)

第一种方法的问题是它返回一个浮点数(即3.0).第二种方法感觉笨拙且时间太长.

The problem with the first approach is that it return a float (namely 3.0). The second approach feels clumsy and too long.

是否有其他解决方案可以在Python中使用地板?

Are there alternative solutions for taking floors in Python?

推荐答案

只要您的数字为正，就可以简单地转换为int以四舍五入到下一个整数:

As long as your numbers are positive, you can simply convert to an int to round down to the next integer:

>>> int(3.1415)
3

对于负整数，这将四舍五入.

For negative integers, this will round up, though.
