•Precision is basically the same as that described under “Calculation Range and Precision”, above.

•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.
