[Setting data]
Setting data Description Data type of result
(S1) Multiplicand data
(S2) Multiplier data
Data type of (S1) or (S2)
which is greater
[Functions]
(1) The data specified with (S1) is multiplied by the data specified with (S2).
(2) When (S1) and (S2) differ in data type, the data of the smaller data type is
converted into that of the greater type before operation is performed.
[Errors]
(1) An operation error will occur if:
• (S1) or (S2) is an indirectly specified device and its device No. is outside the
range.
[Program examples]

The 64-bit floating-point type data are used for multiplication, and the result is
converted into the 32-bit integer type and then substituted.
