Finding small equation solutions with great precision with Solvesys and Longfloat

[John Keith]

The point that I was trying to make is that in either case you will have do do your own programming. SolveSys and LongFloat will not work together as-is. Both of those libraries are large and complex, and integrating or re-writing them will not be a trivial task.

If you are in exact mode (equal sign rather than tilde in the top line of the status area) pressing 3 ENTER 5 / will return '3/5' rather than .6. For example from your link, 127*10^-12 will evaluate to '127/1000000000000'. Once again, you will have to write your own solver program to work with exact arguments.
