Abstract

PURPOSE: To attain great reduction in operation time by letting an arithmetic circuit multiply a read factorial value by integer values continuing from reference data to following input data.
CONSTITUTION: In ROM14, factorial values of reference data of integers at fixed intervals are previously stored and keying operation is performed by key input part 13. Here, gate circuit 11 is opened by a signal outputted by instruction decoder 9 to read from ROM14 a factorial value corresponding to reference data smaller than and closest to or equal to input data, and it is sent to address assignment part 15. Then, the read factorial value is multiplied by arithmetic circuit 5 by respective integer values continuing from reference data to following input data. Consequently, there is no need for multiplication by all integer values until input data at every time, so that the operation time can be shortened greatly.
