20130409 18:14:34< AI0867> mattsc: how come the default min hp cutoff is -1? (and why is the default larger than -infinity?)
20130409 18:15:31< mattsc> AI0867: ooo, somebody actuallt looks at the code!  :)
20130409 18:16:11< mattsc> The reason is that min_hp is always non-negative, but not all min_hp = 0 are the same (equally bad).
20130409 18:16:43< mattsc> While average_hp = 0 means that the unit *will* die, min_hp = 0 can have different CTKs.
20130409 18:17:41< mattsc> Thus, I shouldn't stop checking other combinations if min_hp = 0, and any negative number will do as default..
20130409 18:17:44< AI0867> ah, okay
20130409 18:18:12< AI0867> you might want to note that in the comments
20130409 18:18:40< mattsc> AI0867: will do.  Thanks.

20130409 18:24:09< irker013> This explains why default value is -1.
20130409 18:27:15< mattsc> AI0867: that reminds me that I've been meaning to check whether Lua has constants for inf and -inf.
20130409 18:27:38< mattsc> I'm always using -9e99 which feels ... inelegant at best...
20130409 18:35:43< AI0867> hmm, how many nines do you need to overflow a double?
20130409 18:42:40< AI0867> python says that 9e999 is inf, while 9e99 is 9e99
20130409 18:43:47< AI0867> this holds for python2.7 and python 3.2, positive and negative

20130409 18:44:48< AI0867> the last column is the maximum "e value"
20130409 18:45:32< mattsc> AI0867: I see.  Thanks.
20130409 18:46:18< mattsc> In my applications, -9e99 is plenty negative.  I compare that to numbers that usually don't go below -100, and rarely below -1000.
20130409 18:46:47< mattsc> It's more a "general principle" thing than an actual problem in the AI code.
