! type functions require consecutive internal calculation, which
can cause accumulation of errors that occur with each calculation.
• Error is cumulative and tends to be large in the vicinity of a function’s singular
point and inflection point.
• The range for calculation results that can be displayed in
P
form when using

. Note, however, that internal calculation error
can make it impossible to display some calculation results in
P
form. It also
can cause calculation results that should be in decimal form to appear in
P
form.
