can make it impossible to display some calculation results in π form. It also
can cause calculation results that should be in decimal form to appear in
π form.
Errors
The calculator will display an error message whenever an error occurs for
any reason during a calculation. There are two ways to exit an error message
display: Pressing d or e to display the location of the error, or pressing
A to clear the message and calculation.
Displaying the Location of an Error
While an error message is displayed, press d or e to return to the
calculation screen. The cursor will be positioned at the location where
the error occurred, ready for input. Make the necessary corrections to the
calculation and execute it again.
When you input 14 ÷ 0 × 2 = by mistake instead of 14 ÷ 10 × 2 =
B
14 / 0 * 2 =
e (or d)
d 1 =
Clearing the Error Message
While an error message is displayed, press A to return to the calculation
screen. Note that this also clears the calculation that contained the error.
Error Messages
Math ERROR
Cause: • The intermediate or final result of the calculation you are performing
exceeds the allowable calculation range. • Your input exceeds the allowable
input range (particularly when using functions). • The calculation you are
performing contains an illegal mathematical operation (such as division
by zero).
Action: • Check the input values, reduce the number of digits, and try again.
• When using independent memory or a variable as the argument of a function,
make sure that the memory or variable value is within the allowable range
for the function.
Stack ERROR
Cause: • The calculation you are performing has caused the capacity of the
numeric stack or the command stack to be exceeded. • The calculation you are
performing has caused the capacity of the vector stack to be exceeded.
Action: • Simplify the calculation expression so it does not exceed the
capacity of the stack. • Try splitting the calculation into two or more parts.
