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

^(xy), x'y, 3', 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.
