Add Logic to Workflow message templates (Email+ pdf) formular

I need to specify some more details on the contibution (off-line) mail & pdf-Formular which is generated out of HTML editior.
How is it possible for example to calculate the actual amount in to a 2nd value with other currency and display it separately?
Can I use Java Script there, for calcuating and 'printig' in the eMail text an in the pdf - file? Examples ?

Thanx to any advices, Markus
