Abstract

PURPOSE: To make it possible to complete a constant calculating function in either case, an operand and operated operand, by enabling an operator to set freely whether a stored constant should be the operand or operated operand.
CONSTITUTION: Constant information memory indication key SK on keyboard K is enable to function to transfer the contents of display/arithmetic register X, arithmetic indication information memory part F and calculation state memory part N to memory part SN stored with information showing whether numeral memory part SX, arithmetic indication information memory part SF and memory part SN of constant-calculating memory part S is memorizing an operand or operated operand. With key SK operated, arithmetic control part C judges the contens of memory part N to output control signal 1 or 2 according to arithmetic indication information, and consequently AND gate G1WG3 or G4WG6 are turned ON, so that the stored constant can freely be set to the operand or operated operand.
