Caution for using operand
If a remainder by 16-bit division should be recorded, use DIV / DIVP
instruction instead.
If a remainder by 32-bit division should be recorded, use DDIV /
DDIVP instruction instead.
Description
S
1
: Dividend
S
2
: Divisor
D: Quotient
DIV16 and DIV16P are 16-bit instructions. DIV32 and DIV32P are 32-bit instructions.
The singed binary value in S
1
is divided by the signed binary value in S
2
, and the quotient is
stored in D. It is not a normal algebraic regulation. Be careful with the positive / negative signs
of S
1
, S
2
and D when doing 16-bit and 32-bit operation.
If the divisor is 0, the instruction will not be executed. M1067 and M1068 = ON, and the error
code in D1067 is H0E19.
In 16-bit BIN division,
When D serves as a bit device, it can designate K1–K4 and construct a 16-bit result, occupying
a 16-bit quotient.
In 32-bit BIN division,
When D serves as a bit device, it can designate K1–K8 and construct a 32-bit result, occupying
a 32-bit quotient.
Example
Example 1
When X0 = ON, the dividend K103 in D0 is divided by the divisor K5 in D10, and the quotient is
stored in D20. ON / OFF of the highest bit indicates the positive / negative status of the result
value.
