ABSTRACT:
A round-off type of numeric data display apparatus which has at least X, Y, Z and K registers, and which stores in said X register a previous data item obtained by a previous one of arithmetic operations convergently producing a result in turn, stores in said Y register an immediately succeeding data item obtained by an immediately succeeding one to said previous one of said arithmetic operations, stores in said K register that number of digit-place data items to be rounded-off of said immediately succeeding data item which has been obtained by the arithmetic operation in an arithmetic-operational section connected to said X, Y, Z and K registers, subjects said immediately succeeding data item to rounding-off operation in said arithmetic-operational section on the basis of the contents item of said K register and stores the result of said rounding-off operation in said Z register, transfers the contents item of said Z register and a decimal point code of said Y register to a display buffer connected to said Y and Z registers, and displays only numeric data of reliable digit-place number from a display section connected to said display buffer.
