5.9.3 Divide
Divides the operand IN1 by the operand IN2 of the same data type as IN1 and stores
the quotient in the output variable assigned to Q, also of the same data type as IN1
and IN2.
The result is output to Q when DIV is performed without Overflow, unless one of the
following invalid conditions occurs:
▪ 0 divided by 0 (Results in an application fault.)
▪ IN1 and/or IN2 is NaN (Not a Number).
If an Overflow occurs, the result wraps around.
Notes:
▪ DIV rounds down; it does not round to the closest integer. For example, 24 DIV 5 = 4.
▪ Be careful to avoid overflows.
