What is the internal accuracy for Pi in the DM-42?

There is a discussion of the correct result of SIN of exactly 3.141592654 Radians in the HP 15C Advanced Functions handbook Appendix...The Dm-42 gets it correct to a full 34 significant digits, (as I verified in Mathematica...).

Re: Anything I should know before I install the USB Driver for the DM42...

You mentioned..."The Wizard may suggest to reinstall; if so, do so, but this is a normal startup, you do not need to do the unsigned driver thing again, as the drivers are now installed.". I am wondering if it does ask to reinstall, do i reinstall in driver verify disble mode once again, or do i rei...

Re: Anything I should know before I install the USB Driver for the DM42...
