k 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 are performing causes the
capacity of either stack to be exceeded.
k 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.
Calculation Range and Precision
Calculation Range ±1 × 10
–99
to ±9.999999999 × 10
99
or 0
Number of Digits for Internal
Calculation
15 digits
Precision In general, ±1 at the 10th digit for a single
calculation. Precision for exponential display
is ±1 at the least significant digit. Errors are
cumulative in the case of consecutive
calculations.
