I'd also add that the digits are placed in the X-register, not into the calculator as in some unknown place... (I still have my head back in the 80's, when manuals usually cleared issues instead of bringing them in...)

I couldn't find a list of known bugs in the original manual so sorry if this is not new.
Only minor but page 24 of the 15C Owners Handbook says "Pressing [g][pi] places the first

10 digits of pi into the calculator."

However, strictly speaking, the calculators (both original and LE) do not do this. Instead [g][pi] places a *rounded to 10 digits* approximation to Pi into the calculator. (And the example on page 62 gets this right.)

Actually, it doesn't put it into the calculator either. It's already there. Rather it moves it into the X register. Or better yet it makes a copy of the constant rounded to 10 places and puts it into the X register, which is really a BCD representation of the decimal number system, and not the actual number itself. (assuming of course it doesn't calculate it on the fly)

So that's why I've been getting all those wrong answers! :-)
