Abstract

PURPOSE: To perform an easy-to-see display at a desired digit place and through the key operation of one time, by providing plural mark keys that show the prefixes of an integer multiplication of 10 and then converting the unit of the display data by operating these mark keys.
CONSTITUTION: Mark keys M, K, m and u showing the prefixes of 106, 103, 10-3 and 10-6 times that show the prefixes of an integer multiplication of 10 are provided at an input part of a small-sized electronic computer. After a numerical data is supplied by a ten key 2a, a mode key 2c and a mark key are selectively operated to write the corresponding component data into a component buffer B1 in a memory 9 via a control part 4. At same time, the contents of the memory 9 data are fed to a unit mark display part 12 via an arithmetic part 8 and a gate circuit G, and the numerical value receives an integer multiplication of 10 to be displayed at 11. At the same time, the corresponding prefix is also displayed.
