CiviCase - Placing calculated fields within a case

[FETmz]

When creating a case is there a possibility to make two custom data fields be able to perform a calculated field result for example:
The quantity of Bananas multiply the price of the bananas = total amount owned [Number x price = total amount]

Therefore the two data fields that have data entered within them are able to make an automatic calculations without the user requiring to manual acquire it? Is it possible to make a connection between two separate data fields?

Thank you in advanced!

I don't think this is possible with built-in features, but there are several methods for customizing that should work. Maybe some jquery in a .extra.tpl file. http://book.civicrm.org/developer/current/techniques/templates/

I would use hook_civicrm_CaseSummary to display the extra info.
