Description
The 8-digit BCD equivalent constant or the 8-digit BCD data specified by S1 is divided by the 8-digit BCD
equivalent constant or the 8-digit BCD data specified by S2. The quotient is stored in the areas specified by
D+1 and D, and the remainder is stored in special data registers DT9016 and DT9015 (DT90016 and
DT90015 for FP0 T32/FP0R/FPΣ/FP−X/FP2/FP2SH/FP10SH).

When processing 8-digit BCD data, the higher 16-bit areas (S1+1, S2+1, D+1) are automatically determined
once the lower 16-bit areas (S1, S2, D) are specified.
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 8-digit BCD equivalent constant or the 8-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”.
