#3 64-bit compiler support
this package seems to be for 32-bit systems (where long and int are the same size).
The first clue: the is no ultoa.
The second clue: in ulltoa_general there is a check to see if the number is > ULONG_MAX and a comment saying to do div64 bits, then 32 bits. But ULONGLONG is actually 128 bits in 64-bit systems.
I guess one could rename the functions and types to support 64-bit longs and 128-bit long long but i wonder if the author could share some thoughts and ideas on this. Maybe an update to the package could be provided.
Hi Edwin,
Indeed this package is not perfect, to be completely honest I do not
need it at the moment, so I put it a bit apart (For the moment).
I have attached more mature versions if they are needed.
I have no 128 platform at the moment.
If you wish, I can promote you as co-developer of this small project. I
am vastly interested by any fomr of cooperation on this, because it
always was a surprise to see that no much effort is put on this feature.
Thanks for you interest, have anice day.
Regards
Remi

I got it to work for 64-bit.
I see what the deficiencies were. On 32-bit, long long was 64-bit but on 64-bit, long and long long are 64-bit. I know how to best fix it too: use int32_t and int64_t instead. I would like to take on your offer to become a co-developer and address these 64-bit issues…just give a month or so to make the changes.
Thanks,
Edwin

Hi Edwin,
I added you as a developper of this project. Tell me if this is not enough.
For your information, this code is in production at New York stock
exchange, where it is about three times faster than their itoa
implementation.
Also, for you information, there might be firther improvements based on SSE
instructions.
Best regards
Remi
