ABS

The ABS command is a mathematical function that returns the absolute value of a number. In essence, it removes the negative sign from a number, always returning a positive or zero value. The parameter expression is the value whose absolute value you want to calculate. This can be a constant numeric value, a variable, or a mathematical expression.

The ABS command is very useful in several situations. When calculating the distance between two points, the absolute value ensures that the distance is always positive, regardless of the order in which you consider the points. You can use ABS inside conditions to test whether a value is greater than or less than a certain threshold, ignoring the sign. In many applications, you need to work with absolute values to avoid errors or unexpected results.

The ABS command can be applied only to integers.
