E Stack Limitations
This calculator uses memory areas called stacks to
temporarily store lower calculation priority sequence
values, commands, and functions. The numeric stack
has 10 levels and the command stack has 24 levels,
as shown in the illustration below.

A Stack ERROR occurs when the calculation you аге
performing causes the capacity of either stack to be
exceeded.
E Calculation Ranges, Number of Digits,
and Precision
The calculation range, number of digits used for internal
calculation, and calculation precision depends on the
type of calculation you are performing.

Internal Calculation
Precision
In general, +1 at the 10th digit for
а single calculation . Precision for
exponential display is +1 at the
least significant digit. Errors
are cumulative in the case of
consecutive calculations.

digits or less(including division marks).
* Precision is basically the same as that described under
"Calculation Range and Precision ", above.
* ^(x')Aly,A Xt, 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.
E Error Messages
The calculator will display an error message when a
result exceeds the calculation range, when you attempt
an illegal input, or whenever any other similar problem
occurs.
When an error message appears:
The following are general operations you can use when
any error message appears.
*Pressing (ӨО or) displays to the calculation
expression editing screen you were using before the
error message appeared, with the cursor located at
the position of the error. For more information,
see "Displaying the location of an Error".
* Pressing [АС clears the calculation expression you
input before the error message appeared. You can
then re-input and re-execute the calculation, if you
want. Note that in this case, the original calculation
will not be retained in calculation history memory.
