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)
÷ binary floating point (D11, D10) and the quotient is stored in (D21,
D20).

Program Example 2:
When X2 = On, binary floating point (D1, D0) ÷ K1234 (automatically converted into binary floating point
)
and the
result is stored in (D11, D10).
