Abstract

PURPOSE:To perform easy to see digital display by displaying numerical values together with unit symbols such as ''sen'' (thousand), ''man'' (10 thousands), and ''oku'' (one hundred million). CONSTITUTION:Keyboarded values enter a display register DR through an arithmetic processing unit CPU. If the ''man'' and ''sen'' of unit keys are inputted, the values of the register DR are changed to unit multiples. Since the values below the units are unregistered numbers, a symbol other than 0-9, for example, E of hexadecimal numbers is beforehand put therein. Further, F of hexadecimal numbers is beforehand put in the unnecessary Os of upper priority digits. The register DR drives a display device 2 by means of a decoder driven DEC. Here, if, for example, an operation key is pushed, the contents of the display register are inputted to a detecting circuit DT, by which the detection of the contents is accomplished, thence conversion is carried out by the CPU is accordance with the respective units.
