STAT

* 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 ^(

y, x!,

, nPr, nCr, etc.)

In the vicinity of a function’s singular point and point of inflection, errors are cumulative and may

become large.
