Java中的Double.MIN_VALUE大于零？ [英] Is Double.MIN_VALUE is greater than zero in Java?

问题描述

我在代码中发现了一个错误，它将 Double（0.0）与 Double.MIN_VALUE 进行比较。基本上，以下返回false：

I found a bug in my code which boiled down to comparing Double(0.0) with Double.MIN_VALUE. Essentially, the following returns false:

System.out.println(0.0 > Double.MIN_VALUE);

这可能如何？

推荐答案

根据 javadoc对于Double.MIN_VALUE ，MIN_VALUE是：

According to the javadoc for Double.MIN_VALUE, MIN_VALUE is:

持有最小
正值非零值的常量double = / p>

A constant holding the smallest positive nonzero value of type double

所以Double.MIN_VALUE不是负数，它的正值与Double可以达到零（不为零）一样接近。

So Double.MIN_VALUE is not negative, it's the positive value that's as close as a Double can get to zero (without being zero).
