• x , √y, √ , x!, nPr, nCr 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 π form when
using Natural Display is |x| < 10
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.
