Value is a numeric global variable.

Value also has a toggle bar to the right of the number that allows you to vary the numeric data. The range that you have available depends on its latest value.

You can use a Value in any field that accepts a numeric value, whether an mathematical expression or the point size in a command.

Being able to quickly vary a value is useful when you are using the variable in a function and want to understand how the function changes with a given variable.
