Notes on operand usage:
Refer to the function specifications table for each device in series
for the scope of device usage.
 S
1
: multiplicand. S
2
: multiplier. D: product.
 Multiplies the content of the register designated by S
1
by the content of the
register designated by S
2
, and stores the product in the register designated by
D; multiplication is performed entirely using binary floating point numbers.
 If the source operand S
1
or S
2
designates a constant K or H, the command
converts that constant into a binary floating point number for use in
multiplication.
 In the situation when S
1
and S
2
designate identical register numbers, if you
employ a "continuous execution" command, when conditional contact is ON, the
register performs multiplication once during each scan. You generally use pulse
execution type commands (DEMULP) under ordinary circumstances.
 When X1 = ON, multiplies the binary floating point number (D1, D0) by the
binary floating point number (D11, D10), and stores the product in the register
designated by (D21, D20).
X1
DEMUL D0 D10 D20
 When X2 = ON, multiplies the binary floating point number (D1, D0) by K1234
(which is automatically converted to a binary floating point number), and stores
the results in (D11, D10).
