Changing Of The Guard

[Matt Agajanian]

Mike, Yes, indeed. Even as I remember from my SR-56 days, TI would always reprint that guard digits/ EE/INV-EE guard digits example even in its TI-58/59 and TI-57 manuals among others to show that guard digits were present in calculations.

Thomas, thanks for the verification. Although, as I regard HP in high technological respect, their usage of guard digits in their calcs is quite obscure and I do not recall in any manuals that calculations are carried past 10 digits of accuracy (unless it's explicitely stated in some of their manuals and I must've missed the fine print somwhere).
