* For a single calculation, calculation error is
±
1 at the
10th digit. (In the case of exponential display, calculation
error is
±
1 at the last significant digit.) Errors are
cumulative in the case of consecutive calculations, which
can also cause them to become large. (This is also true
of internal consecutive calculations that are performed
in the case of ^(

In the vicinity of a function’s singular point and point of
inflection, errors are cumulative and may become large.
Users of other models should refer to the “User’s Guide 2
