Error Conditions
Some calculator operations cannot be performed under certain conditions (for
example, z when x = 0). If you attempt such an operation under these condi-
tions, the calculator will display the word Error followed by a digit, 0 through 9.
Listed below are operations that cannot be performed under the conditions spec-
ified. The symbols x and y represent the number in the X- and Y-registers,
respectively, when the operation key is pressed.
