O/OVERFLOW
Overflow takes place when an answer, whether intermediate or final,
or an accumulated total in the memory exceeds 8 digit integers {or 7
digits, when the figure is negative.) in all calculations and is indicated
by the

sign, stopping further calculation. To release the locked
registers caused by the overflow check, depress the £3 key.
