Pantheon Simulation needs more digits

[rilitili]

Is your feature request related to a problem? Please describe.
The Pantheon floors are starting to show 0% success chance.

Describe the solution you'd like
I would like more digits, 0,001235% will be useful to compare for example which equipment/setup is stronger.

Describe alternatives you've considered
Make the tooltip show more digits if you don't like the extra UI clutter.

Additional context
It's just so we can optimize Pantheon and save some Kobans in the process.

In the same vein, if the fight is impossible would it be possible to get information about the opponents left HP% in the simulation (min/max/avg)?
This would be helpful to tell if it is close and might be worth to use a mythic booster to get through that XX00 stage.
