I like to know the logic of getting the sign of a variable. I don't want any
code. One way of doing it is by dividing the vaiable by its absolute value.
But what will happen if the variable is zero? So this method doesn't work.
What is the alternative?

One method I've used is comparing the variable to its absolute value - if they match, it's positive. If they don't, it's negative.
