8 Application Instructions API 100-149 API 123 Operands: S 1 : Dividend S 2 : Divisor D : Quotient and remainder Explanations: 1. See the specifications of each model for their range of use. 2. Flags: M1020 (zero flag); M1021 (borrow flag); M1022 (carry flag) 3. S 1 S 2 D . The floating point value in the register designated by S 1 is divided by the floating point value in the register assigned by S 2 and the result is stored in the register designated by D . The division is conducted in binary floating point system. 4. If S 1 or S 2 is an designated constant K or H, the instruction will convert the constant into a binary floating point value before the operation. 5.
If S 2 = 0, operation error will occur, the instruction will not be executed, M1067, M1068 = On and D1067 will recorded the error code H’0E19. 6. If the absolute value of the result ＞ maximum floating point available, the carry flag M1022 = On. 7. If the absolute value of the result ＜ minimum floating point available, the borrow flag M1021 = On. 8. If the result = 0, the zero flag M1020 = On. Program Example 1: When X1 = On, binary floating point (D1, D0) ч binary floating point (D11, D10) and the quotient is stored in (D21, D20). X1 Program Example 2:
When X2 = On, binary floating point (D1, D0) ч K1234 (automatically converted into binary floating point ) and the result is stored in (D11, D10). X2 Remarks: For floating point operations, see “5.3 Handling of Numeric Values”.
