The WP 34S does not use Intel's library. It uses the decNumber library for the basic operations and everything else is implemented on top of this. I'm aware of a couple of instances where the 34S rounds correctly whereas Intel's library is off by one in the last digit. I'm not aware of the reverse (yet).

Thanks for the information and your kind work. I purchased a hard copy manual and enjoy it as well.
