Happy Birthday Ed Trefzger!!

Re: Happy Birthday Ed Trefzger!!

Seriously though. Change the code to long double and you could pound away for a year and probably not hit the max. maybe you could depending on how it's stored but whatever. Some of us are still relatively new here. While it says i've been around since 07, don't kid yourself, I've posted maybe 100 times before 2010.

Must we go into this again? By the way that Rep works, the only important thing is the Rep Doubling Time which was about 6 days in the summer of 2007. It would take us an additional 32 times that to max out again with a concerted team effort.

jeebus. I'm sorry for being new and not digging through the hundreds of threads. (Also worth noting that a long double would take far longer since it's 128 bits rather than the approximately 2^32 it's at now)

I wouldn't question RalphPa on the math in rep. ;)

There's a lesson from a vet to a noob. :D

Oops, then it is 96 more doublings which would indeed take well over a year.

Seroiusly, why do it? Rep is broken, and it isn't worth fixing. Ed has a lot more important things to work on.
 
Re: Happy Birthday Ed Trefzger!!

Which is why I said depending on how it's stored. Since it appears the max is around 2^32, that would be an "integer" in most languages. Simply increasing it to a "long" would go from 2,147,483,647 to 9,223,372,036,854,775,807. Now, increasing it to a long double, supposing that the board can handle that and the server doesn't throw up all over itself, a long double in C would give you 1/2*2^80 for a max value. That's a big friggin number.

I was wrong when I said 128. Sounds like 80 bits is used in C. And it's all coming back to me now... Stupid computer programming classes... They were only useful when it came to passing numerical methods back during my senior year.

I agree. Instead of crashing the server by just loading rep for all users, i'd rather he do something productive. :D :D :D

The max is 2^31 - 1, not 2^32 - 1 since the 32-bit word is signed. That is indeed 2,147,483,647.

Could you explain what 1/2*2^80 represents?

I agree completely with he last statement.

Essentially 2^79 - 1. Kind of like instead of 2^32 * 1/2 -1 it's represented by 2^31 - 1. Sorry about that. Stupid notation on my part.:o
