Dividing 32-Bit Binary Data - Mitsubishi Electric MELSEC iQ-F FX5 Programming Manual

Dividing 32-bit binary data

D/(P)(_U) instruction and DDIV(P)(_U) instruction can be used for division of 32-bit binary data.
D/(P)(_U)
These instructions divide the 32-bit binary data in the device specified by (s1) by the 32-bit binary data in the device specified
by (s2), and store the result in the device specified by (d).

Processing details
• These instructions divide the 32-bit binary data in the device specified by (s1) by the 32-bit binary data in the device
specified by (s2), and store the division result in the device specified by (d).

• For the division result of word device, 64-bit binary is used to store the quotient and remainder. For bit device, 32-bit binary
is used to store quotient only.
