Use the abs function if you need to know the magnitude of the number and are not concerned about whether it is negative or not.

The absolute value of a number is that number's distance from zero. If the number is positive, its absolute value is just the number; if the number is negative, its absolute value is the negative of the number. Because of this, the absolute value of a number is always positive.
