Abstract

PURPOSE:To easily execute a fractional calculation by a simple consitution, by changing an inputted fractional data to a decimal, executing the operational processing to the decimal data, and changing its result to a fraction. CONSTITUTION:A data inputted from a key input part 11 is inputted to an operation control processing part 13. In case said data is a fraction, it is returned to the processing part 13 as a decimal data through a fraction decimal converting part 14, and a result of the operation is displayed on an indicator 15. Also, in order to convert the operation result to a fraction, the data is converted to a fractional data by a decimal fraction converting part 12, is returned to the processing part 13, and is displayed 15.
