Im quite new to Captivate and I wanted to implement some powers or square root calculations in a project.
I found the basic arithmetic actions under advanced actions, but this is only for +-*/
The only solution I could think of for powers is creating a loop through conditional actions to multiply a variable by itself over and over again and save it as another variable, but this would only work for integers.
Any help you can give me would be appreciated
At this point in time Captivate's Advanced Actions don't offer anything other than very basic math calculation capabilities, as you have discovered.
If you want more powerful functionality, you should log an enhancement request for Captivate 6 as soon as possible (because they've started working on it).
In the meantime, if this kind of functionality is essential to your project, your next best alternative is probably to engage an ActionScript 3 developer to create a widget for you that can do what you want. But be warned that custom-built widgets can take days or weeks to complete and can cost hundreds or even thousands of dollars in developer time.
Actually, I just remembered that there might be another way to achieve what you want.
