Calculator capable of calculating with additional externally instructed units

摘要

Electronic data processing equipment such as an electronic computer is provided which is capable of specifying the radix or unit of input numerical data entered together with the radix or unit information manually keyed-in or automatically identified even without receiving such information. A number expressed in one radix or unit is converted into a number expressed in another radix or unit so that the arithmetic operations between the numbers expressed in different radices or units will be executed in a common radix or unit. The result may be displayed in either one of the radices or units.
