DMULR, DMULRP: 13 steps

Operands:
S
1
: Floating point multiplicand
S
2
: Floating point multiplicator
D
: Product
Explanations:
1.
S
1
and
S
2
can be floating point values (FX.XX).
2. See the specifications of each model for their range of use.
3. Flags: M1020 (zero flag), M1021 (borrow flag), M1022 (carry flag)
4. In DMULR instruction, floating point values (e.g. F1.2) can be entered directly into
S
1
and
S
2
or stored in register
D for operation. When the instruction is being executed, operand
D
will store the operation result.
5. When
S
1
and
S
2
stores the floating point values in register D, their functions are the same as API 122 EMUL.
6.
S
1
and
S
2
can designate the same register. In this case, if the “continuous execution” type instruction is in use and
during the On period of the drive contact, the register will be multiplied once in every scan by a “pulse execution”
type instruction (DMULRP).
10. If the absolute value of the operation result is larger than the maximum floating point displayable, the carry flag
M1022 will be On.
11. If the absolute value of the operation result is smaller than the minimum floating point displayable, the borrow flag
M1021 will be On.
12. If the operation result is “0”, the zero flag M1020 will be On.
Program Example 1:
When X0 = On, the floating point F1.20000004768372 will multiply F2.20000004768372 and the result
F2.64000010490417 will be stored in the data registers (D10, D11).

Program Example 2:
When X1 = On, the floating point value (D1, D0)
× floating point value (D11, D10) and the result will be stored in the
registers designated in (D21, D20).
