•Precision is basically the same as that described under
“Calculation Range and Precision” on page E-137.

', 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.
