Re: What city or town is the DM-42 made??

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...).
