When the content of the register designated by S
the register designated by S
designated by D; multiplication is performed entirely using binary floating-point
numbers.
If the source operand S
transform that constant into a binary floating point number for use in
multiplication.
In the situation when S
"continuous execution" command is employed, when conditional contact is On,
the register will perform multiplication once during each scan. Pulse execution
type commands (DEMULP) are generally used under ordinary circumstances.
When X1=On, the binary floating point number (D1, D0) will be multiplied by the
binary floating point number (D11, D10), and the product will be stored in the
register designated by (D21, D20).
X1
When X2 =On, the binary floating point number (D1, D0) will be multiplied from
K1234 (which has been automatically converted to a binary floating-point
number), and the results stored in (D11, D10).
