Divide by Zero

(1/1)

Shasta:
I was trying to write a new bot and came across a few questions that I couldn't find an answer for.

What value does a divide by zero return? I saw in DB 3 it will yield a 0 is this true for 2.4x also?

True and False can be used to control whether parts of genes execute, can conditional operators be used to control them?
For example I have a gene (Which I doubt works, as this computer cant really run DB I cant test it) that asses if the bot is being hurt to much and should run away:

--- Code: ---'See If I Am Being Hurt Too Badly
cond
 *.wellness 0 <=
start
 628 rnd 314 add .aimsx store
 *.maxvel .up store
 *.welltime 4 mod 0 =
 0 .wellness store
stop
--- End code ---

Finally,

--- Code: --- *.refnrg *.refkills div *.nrg *.kills div div 1 >=   'Less than one is bad/dangerous
--- End code ---
Would there be a better option for checking if the bot in eye5 is worth attacking? This one would have problems depending on what a divide by zero returns (veggies) and for low energy bots and a couple of other problems, such as never finishing off bots.

Edit: Also how many cycles does poison last for, is it the same as venom?

Sorry for all of the questions

It's 0 too.  Generally any command that's mathematically invalid will return 0.  (like sqrt(-number)).

Yes.  You don't even need to break up your genes into cond and start blocks even.

Yep, same as venom.  1 cycle per unit.

Not at all.
