Abstract: PURPOSE:To make the increase in the circuit scale and wiring slight even when an expanded data length is large by giving a clock of a prescribed shift number of times to an N+l bit of register with a signal representing the shift so as to convert the data. CONSTITUTION:A shift means 83 is used to input 3 clocks to 6-bit shift registers FF6-1 and selectors 93-91 select signals A2-A0 of an effective n-bit at the initial clock, the selector 93 output a selection signal selecting an output of the high- order FF6 and the selectors 92, 91 output a selection signal selecting the output of the high-order FF at succeeding clocks. Then a signal A2 is outputted from outputs Y5-Y3 of FF6-FF4, a signal A1 is outputted from an output Y2 of the FF3, a signal A0 is outputted from an output Y1 of the FF2 and 0 is outputted from an output Y0 of the FF1 respectively and a data of a fixed decimal point representation in desired 6-bit is outputted. Thus, when the expand ed data length is increased by, e.g. 1 bit, a FF0 is to be provided newly and similar wiring to that for the FF1 is implemented.
