Total of integer, numerator a b/c and denominator must be within 10 digits (includes " " division marks). * For a single calculation, calculation error is ±1 at the 10th digit. (In the case of exponential display, calculation error is ±1 at the last significant digit.) Errors are cumulative in the case of consecutive calculations, which can also cause them to become large. (This is also true of internal consecutive calculations that are performed in the case of ^(xy), x y, x!, 3 x, nPr, nCr, etc.) In the vicinity of a function's singular point and point of inflection, errors are cumulative and may become large. 20050401
