HP HP-16C - Appendix A: Errors and Flags; Functions That Affect Flags

Appendix A
Errors and Flags
Error Conditions
If you attempt an operation containing an improper parameter—
such as referencing a nonexistent flag number—the display shows
Error and a number. To clear an error display, press any one key.
This also restores the display that existed prior to the error
message. Below is a list of error conditions by number.
Error O: Improper Mathematical Operation
(], where x = 0.
(RMD], where x = 0.
(DBL=], where:
o x=0.
e the quotient exceeds a single word size.
(DBLR], where:
e x=0.
e the quotient exceeds 64 bits.
[z ], where x <0.
(1/x], where x = 0 (Floating-Point Decimal mode only).
Error 1: Improper Flag, Window, [FLOAT], or [GTO][")
Number
Attempted flag number greater than 5.
Attempted window number greater than 7.
Attempted number greater than 9.
Attempted [GTO][-] digit greater than 9.
