Hi all,
Right now, chirp stores frequencies as a floating point number. That's convenient (at times) but is fatally flawed because the internal representation is Base-2. That leads to odd behavior like this:
$ python
130.8 * 100
13080.000000000002
There are many places where this bites users and results in very odd behavior. The correct way to fix this is to store the frequency in units of Hertz, which we can represent cleanly with an integer. This is a straightforward change, but a wide-sweeping one. I've spent many hours doing my best to carefully convert every driver in the tree to this mode of operation, as well as all the UI elements. The automated tests have made this much easier, but there is still the extreme possibility for errors.
I would really (really) appreciate it if you developer-types could clone the following tree and bang around on it a bit:

After an initial sniff-test here, I'll push it into the main repository and hope for some more wide-spread testing.
Thanks!
