Description :
The function Division divides A by B and place the result in the specified variable from Q.
The eventual overflow in the result (Q) is ignored.
A division by zero cause an error condition that imply ENO = 0.
Note: the numbers in floating point are represented in the format described in the standard 754-1985 ANSI/IEEE (in single precision). For further representation about the argument, refers to that law.
