Open Slots in the playerstate_t

Two things: if you're working on Tenebrae modesty doesn't help (so you ARE an expert programmer, don't deny it ) and two: does it make much of a difference? Both work, maybe your version is more efficient and the change is noticeable when you use the function a lot but even so JK2 probably has some sort of absolute value function in q_math.c already (I only wrote this because I couldn't use the function from one of the .h files).

in the original int power(int x, int y) function

if (!y) {
       return 0;
   }

this should be

if (!y) {
   if(!x)
       return NULL;
  else
       return 1;
   }

 

seeing as a^0 = 1, except a=0, where 0^0 is undefined

Uh, I'm pretty sure 0^0 = 1.

Hmmm.... that's what my calculator is saying ... but why?

 

0 to the 0th power is 1, in fact, any number to the '0' power is 1, just as a number to the '1' power is itself.

 

Not really useful math, generally, I know that *I* had to whip out the calculator, but then again, I *always* whip out the calculator.

[ASk]

because 0^0 is undefined, and no, there's no point to argue, because it is so, and I have math finals tomorrow so I know.

 

and for ALL other numbers, x^0 = 1

[razorace]

I'm still pretty sure 0^0 = 1. There's no reason why it would be undefined like x/0.

Hmm... I'll check it with my maths teacher on Wednesday, but Windows Calculator gives me 1 and my normal calculator gives me an error. Hmmph.

[recombinant]

Interesting.

 

I was leaning toward undefined, until I read this:

 

http://mathforum.org/dr.math/faq/faq.0.to.0.power.html

 

"Consensus has recently been built around setting the value of 0^0 = 1"

 

 

...which I'm still not real comfortable with, since as the article states, it's an "indeterminate form."
