Abstract
Apparatus including a first memory for temporarily storing numeric data entered by a numeral key, and a second memory for thereafter storing the numeric data which is transferred thereto from the first memory responsive to operation of a storage control key. Further, there is provided a display for displaying a numeral based on the numeric data stored in the first memory. This apparatus makes it possible for an operator to monitor the numeric data which is temporarily stored in the first memory prior to its storage in the second memory, to prevent erroneous data from being stored in the second memory.
