My compiler only supports 32 bit integers and I need to be able to use unsigned 64 bit integers, this code needs to be fast and as small as possible memory wise. Does anyone here have any code or tips?

Btw, the compiler really don't support 64-bit integers and it's name is HighC used on a Vertex RTOS.

For most modern OS/Compilers the long long is the data type you want to use.

This works with GNU & Borland, I am unsure of the others.

Hi ...

you can to use the type __intn
where n is the size..
__int32 x;

create a x variable with 32 bits

__int64 y;
create a variable with 64 bits..
you must to remember that is a int value;

:-) ,
