other than the c99 function all it would need is error (like perror) checking by what I was told

Okay maybe it needs a few more edits than that like instead of i writing in the form 2^i-1

another thing I found is one I tried (don't remember which one) seems that if it rounds up it rounds to 6 could it relate to perfect number and if I find it again and that's true could perfect numbers be used to find the other half ?

Possible Prime finder
 

I have code that someone on bytes.com forum helped me with and if what I think I've found to be true for half of all Mersenne primes to date then I might change it a bit and build it with help from someone more experienced in C . if what I think is true and my program runs as planned within minutes of compiling and building it and running it a new possible mersenne prime to be checked will possibly break the world record with a 64 bit processor i think it should be able to find over half of all possible mersennes under 2 ^ 18 quintillion+ -1 . So anyone want to help me ?

43112639 seems possible but the other 2 I tried rounded to even numbers this rounds to an odd might be one to stay away from but you can try it if you want I'll try and find one that is close to an even answer

Post your code and we might believe you and help you if it turns out to be true. Most claims like this are from cranks although occasionly huge discoveries are not believed because they are revolutionary so am willing to investigate if you post your code.

He already posted [URL="http://www.mersenneforum.org/showthread.php?p=186403#post186403"]his code[/URL] in his Misc Math thread where it belongs.

I think he's demonstrated quite clearly that he is, in fact, a crank.

Can a mod start locking the doors that Science dude is opening?

[/QUOTE]While not specified in #1 "1 point for each word in all capital letters.", one would like to add a few points for lack of punctuation, sentence division, and other problems with their mother tongue.

Also, a few bonus points are in order for the issues coding C and lack of knowledge about how one might find a free version of C. etc.

Yeah, the crackpot index doesn't exactly tailor to this sort of crank.
