Is Double.MIN_VALUE is greater than zero in Java?

Question

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); 

How is this possible?

Answer 1

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

A constant holding the smallest positive nonzero value of type double

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).
