That would explain We, Belgians, use ln for base e and log for base 10. I thought it was common around the world.

Hello, I was looking into the system of distributing arena ratings, when I saw this method used for calculating the chance of winning: 1.0f/(1.0f+exp(log(10.0f)*(float)((float)enemy_rating - (float)own_rating)/400.0f)); This doesn't do the same as what's told on wowwiki: http://www.wowwiki.com/Arena_PvP_system#Arena_rating_system (I don't know if that's a reliable source though). If it would need to do the same as on wowwiki, we'd need to used "ln" (logarithm to the base e) instead of "log" (logarithm to the base 10). It would be: 1.0f/(1.0f+exp(ln(10.0f)*(float)((float)enemy_rating - (float)own_rating)/400.0f)); I haven't tried to understand the ELO system yet, but if someone could explain me where I'm wrong, I'd much appreciate that Thanks, Atari007

Works fine. Thanks!

Why would you compile in x32 when you can run x64?

Probably 8191?

What about a reload per creature? Checking spawns, respawning, new stats, addons loaded, etc...?
