Well, I know less about - GMP if you mean to say GMP has no restriction on space. I have been talking about working with very large numbers. I do know that decimal numbers are stored in binary or...

Thanks.
Very true.(i) I would like to know more about endomorphisms acting on binary sequences. (ii) Are they more/less helpful in factoring? I googled but did not get suitable results.

No idea if I can go faster. Didn't exactly write and compare the two algorithms. Just wanted to try different.

I thought to use endomorphisms and work similar to modular arithmetic -

Start to compare size of two binary numbers minus zeroes at the end. Then just play with the blocks using endomorphisms....

Well, the only problem is there is a certain integer range that is acceptable as space for an integer(signed or unsigned int). There is a problem if you have to check a number like 2^10000019 -1 is...

Thanks. I learnt about GMP. I was talking about ASCII specifications and space a signed or unsigned int occupies. I will explain in next post.

@science man: That is not what I am saying, people use high level language. It converts everything to machine code. My problem is with HLLs and their fixd integer range which makes prime factoring or...

That is a rude message. Is it not? If my question is that trivial to you, then you could have done the honours of answering it. Did you get my post?

Endomorphisms and Factoring

1. I need to find out a program that only deals in machine level 0s and 1s. What I mean is unlike C++, Java, etc...decimals are not converted to binary but it is a program where every number dealing...

Large runs of Mersenne composites

Hi! I am new to this forum and still clueless about how to use manual testing. I tried to post some observations earlier in manual testing. I am not sure whether this current post is necessary.
