Operands:

: Dividend S

: Divisor D: Quotient and Remainder

Explanation:

1. S

÷ S

= D. The floating point value in S

is divided by the floating point value in S

and the

result is stored in D. The division is conducted in binary floating point format.

2. If S

or S

is designated as constant K or H, the instruction will convert the constant into a

binary floating point value before the operation.

3. If S

= 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).

DEDIV

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).
