A Stack ERROR occurs when the calculation you are performing causes the capacity of either stack to be exceeded.
Stack Issues to Keep in Mind for Each Mode
•In the CMPLX Mode, each input value uses two levels of the numeric stack, regardless of whether the input value is a real number or a complex number. This means that the numeric stack effectively has only five levels in the CMPLX Mode.
•The MATRIX Mode uses its own matrix stack, which is used in combination with the
•The VECTOR Mode uses its own vector stack, which is used in combination with the
kCalculation 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.
