6 BASIC INSTRUCTIONS
6.2 Arithmetic Operation Instructions
Multiplying BCD 8-digit data
DB*(P)
These instructions multiply the BCD 8-digit data specified by (s1) and the BCD 8-digit data specified by (s2), and store the
results in the device specified by (d).
■Descriptions, ranges, and data types
■Applicable devices
• These instructions multiply the BCD 8-digit data specified by (s1) and the BCD 8-digit data specified by (s2), and store the
multiplication results in the device specified by (d).
• When (d) is a bit device, only the lower 8 nibbles (32 bits) of the multiplication result are stored, and the higher 8 nibbles (32
bits) cannot be specified.
