Operands
| Operand | Description |
|---|---|
| S1 | The first operand. Entries are 4-digit binary-coded decimal (BCD) data registers or constants. This is the dividend. The 4-digit binary-coded decimal (BCD) value range is H0000 ~ H9999. |
| S2 | The second operand. Entries are 4-digit binary-coded decimal (BCD) data registers or constants. This is the divisor. The 4-digit binary-coded decimal (BCD) value range is H0000 ~ H9999. |
| D | The third operand. Entries are only 8-digit binary-coded decimal (BCD) data registers. D is where the quotient is saved. D+1 is where the remainder is saved. |
Notice
Error Flag (F11.0) Notice
The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type.
F11.0 turns ON when the value of the data for dividing exceeds the data register assigned to S1 or S2.
F11.0 turns ON when the value of the data for S1 or S2 is not binary coded decimal (BCD) data.
F11.0 turns ON when the value of the divisor, S2, is 0.
BCD Operation
The BDIV and BDIVP instructions perform raw Hexadecimal division.
- Only the numbers 0-9 can be used.
- A-F will NOT work.
Tip: Operand Division Format
S1 is divided by S2.
(S1 ÷ S2)
