* 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 signifi cant 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 infl ection, errors are cumulative and may
become large.
