* For a single calculation, calculation error is ±1 at the 10th
digit. (In the case of exponential display, calculation er-
ror is ±1 at the last significant digit.) Errors are cumula-
tive 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 ^(
