Sharp EL-512 - Error Conditions and Clearing Errors; Calculation Range Limits

ERRORS
In the case of an error, the display will show "E ". An error will be caused by a calculations
or instruction beyond the capacity of the machine. An error can be cleared by the @
key. There are three types of error conditions: overflow, underflow, and incorrect opera
tion.
