-The Set Variable to Calculation action sets a variable to the result of a calculation with numeric formatting. Also see the Calculations section.
+====== Set Variable to Calculation Action ======
-{{:action:setvariabletocalc.png|200}}
+The Set Variable to Calculation action sets a variable to the result of a calculation with numeric formatting.
-Select the variable to set from the //Set variable// pop-up or enter a variable name.
+{{:action:km7-set-var-name-to-calculation-action.png?nolink|}}
-Enter a calculation in the //to// text area. The result is displayed at the bottom of the action.
+===== Calculations =====
-Unlike most places you specify a variable, the variable name itself is a text token field, so you can set a variable whose name changes.
+You may use the following in the //to// calculation box:
+  * [[token:Variable|Keyboard Maestro Variables]]
+  * [[:Functions|Functions]]
+  * [[/manual/Calculations|Calculation Operators]]
+The //to// field is a [[:Text_Fields|numeric field]] so you cannot use any of the [[token:CurrentClipboard|Clipboard tokens]] or indeed any [[:Tokens|text tokens]], except within a [CALCULATE](https://wiki.keyboardmaestro.com/function/CALCULATE) function.
+===== Variables =====
+The //to// field is a numeric field, so you use variable names unadorned:
+  * Do **not** use the text token syntax for a Variable, like `%Variable%My Variable Name%`.
+  * Instead, you just use the Variable name without any `%`, like `My Variable Name`
+You can use the //Edit ➤ Insert Function// menu to insert functions.
+===== Formatting =====
+As can be seen by the blue shade of the action gear menu there is an additional option for the action, specifically you can //Format the Result// using [[https://www.stairways.com/action/linkthru?unicodenumberformat|Unicode Number Format Patterns]] such as //#,##0.##//.
+===== Result =====
+At the bottom of the action you can see the current value of the calculation.
+If the calculation is invalidly formatted, the invalid part of the calculation will show up in <color #ed1c24>RED</color>.
+If the calculation would currently fail because an input variable does not currently have a numeric value, that variable will show up in <color #ff7f27>ORANGE</color>.
+===== Examples =====
+==== Example 1 ====
+The below macro performs a simple calculation of adding 1 to the value currently selected by the user in the user's document, and then pasting the new value back into the user's document.
+{{:action:km7-set-var-to-calculation-macro.png?nolink|}}
