Test function for problematic values (machine epsilon)

Test function for problematic values (machine epsilon)

Hello everyone,

I had problems with calculating unavailabilitys in FTAs with the calculation model "Average Unavailability". For small lambdas the Q values can't be calculated correctly and might even be negativ since the precision of the calculation is limited by the machine epsilon/hardware.

I would recommend to implement a examination (+warning alert) which ensures that the user can't insert values for the existing calculations that cause errors in the results.

This would guarantee a higher level of confidence in the Software and save the users the time to check if calculation results are correct /plausible.

Greetings.
