本文介绍了为什么C#允许浮点类型划分非零数字被零?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

为什么C#允许:

1.0 / 0 // Infinity

和不允许:

1 / 0 // Division by constant zero [Compile time error]

在数学上,有积分和浮点之间的差异在被零除点数?

Mathematically, is there any differences between integral and floating-point numbers in dividing by zero?

推荐答案

据微软称,浮点运算溢出或除以零从未抛出异常由于浮点类型是基于IEEE 754,因此有代表无穷大,NaN(非数字)的规定。

According to Microsoft, "Floating-point arithmetic overflow or division by zero never throws an exception, because floating-point types are based on IEEE 754 and so have provisions for representing infinity and NaN (Not a Number)."
