Abstract
PURPOSE: To enable efficient totalizing calculation by informing an operator that the number of times of summing up is ineffective when any other key than a steady calculation key is operated.
CONSTITUTION: Four arithmetic routines described hereafter are available. The (1) multiplication routine (m1→m2→m6→m7→m8) provides usual multiplication or continuous calculation. The (2) routine attains the inhibition of the number of times of summing up in totalization mode. The (3) routine gives effect to constant-angle multiplication in totalization mode. Then, the (4) routine performs steady multiplication in nontotalization mode. Through those flows, it is informed that at least while the key for the steady calculation is not operated in totalization mode, the number of times of summing up in ineffective. As for the imformating method, audio output circuit CVV outputs data stored in registers X and GT by sound via arithmetic circuit Cu.
