',  x !,  n P r ,  n C r  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.

. Note, however, that internal calculation error 
can make it impossible to display some calculation results in π form. It also 
can cause calculation results that should be in decimal form to appear in 
π form.
  Errors
  The calculator will display an error message whenever an error occurs for 
any reason during a calculation. There are two ways to exit an error message 
display: Pressing  d or  e to display the location of the error, or pressing 
 A to clear the message and calculation.
