* For a single calculation, calculation error is p1 at the 10th digit. (In the case of exponential display, 
calculation error is p1 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 ^(
x

),
x

, x!,

, nPr, nCr, etc.)
In the vicinity of a function’s singular point and point of inflection, errors are cumulative and may 
become large.
