Time to read all about them.

I was just about to point you to that thread.

It kind of trails off at the end, as some health issues have caused me to put the TI-95 aside temporarily. I was getting pretty good results with what was discussed in that thread, but the project stalled at needing to find a better iterative solver routine that doesn't fall apart with overflow/underflow in more extreme scenarios. I was just using a direct port of the simplistic root finder from the HP 20S built-in program "library"; strange that the TI-95 doesn't have any kind of built-in solver routine, because it's got a heck of a lot of other cool stuff. I think the math library module might have one, but it isn't really designed for being called from other programs.
