Jarrad, About the sub integers I was a little too easy, because my solution is not as fast as extracting sub integers. What you ask for is what substr is for strings. Now I think this should be added for performance reasons. Regards, Maarten. "Jarrad Waterloo" <jwaterloo@dynamicquest.com> wrote in message news:20060524184833.5667B14A8001@dqmail.dynamicquest.com...
Here are my comments concerning Maarten's infinite precision integer draft. I would not wait to submit this library to boost before these following features because people are in need of it now.
1) The ability to extract sub integers out of an integer such as the integer at bit offset 3 and length of 4. This is especially helpful in the area of RFID where large unsigned integers are partitioned into smaller integers. 2) The ability to convert integer to bases other than base 10; any really from base 2-36 3) An implementation of a fixed sized stack version of the integer_allocator. This may be useful for performance when someone is not working with an infinite precision integer but a very large one such as 512 or 1024 bits. 4) An unsigned version of the integer class that benefits from the higher performance of unsigned operations
