# Examples

# Description
Use the point keyword to find out whether a value can be used in expressions that require a point on the screen.
If the value consists of two numbers separated by a comma or by whitespace, it is a point. The numbers may be non-integers.
If the value is an expression, it is evaluated and LiveCode checks whether the final value is a point. For example, the value of the expression "22 + 3,23" is 25,23 (which is a point), so the following expression evaluates to true:
22 + 3,23 is a point
However, the expression
"22 + 3,23" is a point
evaluates to false, because the double quotes making it a string prevent the expression "22 + 3,23" from being evaluated.
