Double.MIN_VALUE Used Erroneously (Possibly)

[deriven]

I forked the code because I noticed a few places that mistakenly use Double.MIN_VALUE for comparison. But Double.MIN_VALUE is not the lowest negative value for double. Double.NEGATIVE_INFINITY is.

I say "possibly" because I'm not 100% it makes a difference in every possibility. (14 files total.) Some places use it for this.max while others use it for this.actualHigh.

Here's an example where it seems absolutely incorrect.

I can create a PR for this if you agree.
