140 Using the Math Field Module to Compute Values Without the PHP Filter with Caleb Thorne - Modules Unraveled Podcast

## Math Field Module

* What does the Math Field module do?

* Why did you develop it? What hole does it fill?

* You mentioned EntityForm...

* How does it compare to the Computed Field and other modules?

* What are the limitations? When wouldn’t you use it?

* You mentioned before we started recording that you actually rewrote the entire module to use core’s AJAX framework instead of custom jQuery. Why was that? and how did it go?

## Use Cases

* What types of sites do you see this being of most use?

* I might be using this on an upcoming project

## Future

* What are your plans for D8?

* What other general features are planned? I saw the note on the project page about issues with multiple parameters and multivalue fields.
