How to Utilize Default and Custom Variables

By mastering the use of default and custom variables, you can perform complex computations and tailor the functionality of your calculators to meet specific needs. This article will guide you through the process of utilizing both default and custom variables in ActiveCalculator.

Understanding Default Variables

Default variables are automatically linked to your calculator's elements. For instance, a "number" element will have its value stored as a default variable. These variables are essential as they represent the basic data points of your calculator.

Creating and Using Custom Variables

Accessing the Formula Tab

To harness the full power of ActiveCalculator, you'll need to create custom variables. Begin by opening the specific calculator you wish to edit. Then, click on the "Formula" tab, where all the magic happens.

Adding a New Custom Variable

In the formula tab, click on "Add custom variable".

Here, you will enter a name for your variable in the 'Variable Name' field and define the variable field, which is how you'll reference the variable in your formulas.

Writing Formulas Using Custom Variables

To add existing variables into your custom formula, type "@" to bring up a list of all available variables.

You can then select the ones you need for your computation. When writing your formula, remember that ActiveCalculator supports mathjs syntax, allowing for a wide range of mathematical operations.

Integrating Custom Variables into Results

Selecting the Result Element

After setting up your custom variable, you need to integrate it with your results. Select your result element and in the right question tab, look for the source variable dropdown.

Assigning Custom Variables to Results

From the source variable dropdown, choose the custom variable you've just created. This will ensure that the result element displays the value calculated by your custom formula.

Saving Your Work

Once you've configured your variables and formulas, don't forget to save your work. Click the 'Save' button to apply the changes to your calculator. It's always a good idea to test your calculator to ensure the results are accurate and reflect your formulas correctly.

Conclusion

With these steps, you are now equipped to create and use custom variables in ActiveCalculator, opening up endless possibilities for complex calculations. Don't hesitate to experiment and refine your calculators to best serve your needs.
