Cautions
1. Operation result
• The most significant bit of the quotient and remainder indicates the sign (positive: 0, negative: 1) respectively.
• The quotient is negative when either the dividend or divisor is negative.
The remainder is negative when the dividend is negative.
2. Device specified as
• The remainder is not obtained when a bit device is specified with digit specification.
• In a 32-bit operation (by DDIV or DDIVP), Z cannot be specified as
Error
• When the divisor
• A operation error results when the operation result is over 32,767 (16-bit operation) or 2,147,483,647 (32-bit
operation). (Turns the carry flag ON.)
