BIN 32-bit multiplication and division operations
D*(P), D/(P)
Processing details
■D*
• Multiplies BIN 32-bit data designated by (S1) and BIN 32-bit data designated by (S2), and stores the result in the device
designated by (D).
• If (D) is a bit device, only the lower 32 bits of the multiplication result will be considered, and the upper 32 bits cannot be
designated.
Ex.
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 ((D)+2) and ((D)+3) data.
• The values for (S1) and (S2) can be designated at between -2147483648 and 2147483647 (BIN 32 bits).
• Judgments whether (S1), (S2), and (D) are positive or negative are made on the basis of the most significant bit (b31 for
a word device, then transfer the word device data to the bit device by designating ((D)+2) and ((D)+3) data.
• The values for (S1) and (S2) can be designated at between -2147483648 and 2147483647 (BIN 32 bits).
• Judgments whether (S1), (S2), and (D) are positive or negative are made on the basis of the most significant bit (b31 for
(S1) and (S2), b63 for (D)).
(S1): Data to be multiplied/divided or head number of the devices where the data to be multiplied/divided is stored (BIN 32 bits)
(S2): Data for multiplying/dividing or head number of the devices where the data for multiplying/dividing is stored (BIN 32 bits)
(D): Head number of the devices where the multiplication/division operation result will be stored (BIN 64 bits)
(S2): Data for multiplying/dividing or head number of the devices where the data for multiplying/dividing is stored (BIN 32 bits)
(D): Head number of the devices where the multiplication/division operation result will be stored (BIN 64 bits)
