整数5和浮点数5.0之间有区别吗? [英] Is there a difference between an int of 5 and a float of 5.0?

问题描述

除了浮点数有小数点外，我对int为5和float为5.0之间是否存在任何差异感到困惑.

I am confused on whether there is or is not any difference between and int of 5 and a float of 5.0, besides the float having a decimal.

使用int不能使用float进行哪些操作?拥有两个单独的类型，而不是仅仅让所有内容都首先成为float，这有什么意义?

What are some of the things I can do with an int that I can't with a float? What is the point of having two separate types, instead of just letting everything be a float in the first place?

推荐答案

它们是不同的数据类型:

They are different data types:

 type(5)     # int
 type(5.0)   # float

因此，严格来讲，它们并不相同.

And therefore they are not, strictly speaking, the same.

但是，它们是相等的:

5 == 5.0     # true
