Explanation of example
Divides the contents of data register DT10 by the contents of data register DT20 when trigger R0 turns on.
The quotient is stored in data register DT30 and the remainder is stored in special data register DT9015
(DT90015 for FP2/FP2SH/FP10SH).
When H (BCD) 15 is in DT10 and H (BCD) 4 is in DT20, as shown below.

Description
The 4-digit BCD equivalent constant or the 16-bit area for 4-digit BCD data specified by S1 is divided by the
4-digit BCD equivalent constant or the 16-bit area for 4-digit BCD data specified by S2. The quotient is stored
in the area specified by D and the remainder is stored in a special data register DT9015 (DT90015 for FP0
T32/FP0R/FPΣ/FP−X/FP2/FP2SH/FP10SH).

With the FP0 T32,FP0R, FPΣ,FP−X, FP2, FP2SH, FP10SH and FP0 C10, C14, C16, C32/ FP−e, the
numbers of the special data registers are different.

Flag conditions
・Error flag (R9007): Turns on and stays on when:
・Error flag (R9008): Turns on for an instant when:
− The area specified using the index modifier exceeds the limit.
− The data is not BCD data.
− The 4-digit BCD equivalent constant or 4-digit BCD data for the divisor
(specified by S2) is 0.
・= flag (R900B): Turns on for an instant when the calculated result (quotient) is recognized as
“0”.
