====Decrement Variable Node====

This is a [[folder_variable|variable]] node, used to **decrease the value of a numeric variable**.

These are usually used to count changes, totalise values, or along with the [[timing_elapsed|Elapsed]] timing node to create a custom timer.

This node is used in all [[analytic_modules|modules]].
