This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.

Description
The function multiplies the value specified at input s1 by the value specified at input s2. The result
of the function is returned at output d. The result at output 'd' lies between -2147483648 and
2147483647 (i.e. between 16#0 and 16#FFFFFFFF). All 32-bit values are treated as double integer
values.
