Operands:

S1: Dividend S2: Divisor D: Quotient and Remainder

Explanation:

1.S1 ⎟ S2 = D. The floating point value in S1 is divided by the floating point value in S2 and the result is stored in D. The division is conducted in binary floating point format.

2.If S1 or S2 is designated as constant K or H, the instruction will convert the constant into a binary floating point value before the operation.

3.If S2 = 0, operation error will occur, the instruction will not be executed

4.Flags: M1020 (Zero flag), M1021 (Borrow flag) and M1022 (Carry flag)

If absolute value of the result exceeds max. floating point value, carry flag M1022 = ON.

If absolute value of the result is less than min. floating point value, borrow flag M1021 = ON. If the conversion result is 0, zero flag M1020 = ON.

Program Example 1:

When X1 = ON, binary floating point value of (D1, D0) is divided by binary floating point (D11, D10) and the quotient and remainder is stored in (D21, D20).

X1

DEDIV D0 D10 D20

Program Example 2:

When X2 = ON, binary floating point value of (D1, D0) is divided by K1234 (automatically converted to binary floating point value) and the result is stored in (D11, D10).
