6-32
D*(P),D/(P)
6.2.4 BIN 32-bit multiplication and division operations (D*(P),D/(P))
D*(P),D/(P)
Function
D*
(1) Multiplies BIN 32-bit data designated by and BIN 32-bit data designated by , and
stores the result in the device designated by .
(2) If is a bit device, only the lower 32 bits of the multiplication result will be considered, and
the upper 32 bits cannot be designated.
K1.......... Lower 4 bits (b0 to b3)
K4.......... Lower 16 bits (b0 to b15)
K8.......... Lower 32 bits (b0 to b31)
If the upper 32 bits of the bit device are required for the result of the multiplication operation,
first temporarily store the data in a word device, then transfer the word device data to the bit
device by designating ( +2) and ( +3) data.
(3) The values for and can be designated at between 2147483648 and 2147483647
(BIN 32 bits).
(4) Judgments whether , , and are positive or negative are made on the basis of the
most significant bit (b31 for and , b63 for ).
• 0: Positive
• 1: Negative
: Data to be multiplied/divided or head number of the devices where the data to be multiplied/divided is stored
(BIN 32 bits)
:
Data for multiplying/dividing or head number of the devices where the data for multiplying/dividing is stored
(BIN 32 bits)
:
