Variable settings

Learn how to configure parameter behavior in CalcTree, including visibility, default values, and input/output roles.

Access variable settings by right clicking on the parameter on the page, and clicking 'settings.

This will open up the variable settings pane on the right hand side of the screen, looking something like this:

This is where you can control the Display options, name, formula, view, format and rounding and visibility.

Display Options

The display options vary according to the type of variable you defined.

In case of having a matrix or list defined, options like Selection, Tabular Matrix and Options will be available.

Formula

Define the variable’s value using the formula field, which supports MathJS syntax for mathematical expressions and functions (learn more). Formulas can also be defined inline in the document or directly within the variable.

Name

Shows the rendering of the name defined in the formula field.

Format

Adjust the parameter’s display format. Some formatting options may be disabled depending on the parameter’s data type.

Display Precision

Adjust the number of significant decimals to be shown. It doesn't affect the calculation, only the displayed value.

Visibility

Control how the variable appears on the page. For example, you can hide the name and formula when embedding the result in text, or show the full equation and result when illustrating a calculation. By default, all visibility options are enabled when a variable is first created.

Dependancies

Displays a list of all other variables that this variable depends on for evaluation. This helps clarify calculation flow and detect potential circular references.
