Python | 如何强制除法运算为浮点数？ 除数一直舍入为0？

Until the python version 2, the division of two integers was always being rounded down to 0.

在python版本2之前， 两个整数的除法总是四舍五入为0 。

Consider the below example, being executed in python version 2.7,

考虑下面的示例，该示例在python版本2.7中执行，

  1. result = 4/5
  2. print(result)

Output

输出量

  1. 0

Other than overcoming the python version 2.7 which is mostly outdated and not a recommended version, the above-mentioned issue can be resolved while we update the python version to 3.X

除了克服python版本2.7(大多数版本已过时，而不是推荐的版本)以外，在将python版本更新为3.X时，可以解决上述问题

  1. result = 4/5
  2. print(result)

Output

输出量

  1. 0.8

    今天学习了浮点数运算（加减乘除）。浮点数运算主要包括两部分：指数运算和尾数运算。在IEEE754标准下，指数运算就是阶码的运算，类似于无符号数运算。尾数运算是原码运算。之前一直
