DB48X: HP48-like RPL implementation for DM42

[c3d]

I have installed v0.5.1 and I have one bug report and one request:

1- Bug:
Solver>Root struggles to find the root of the following input:
'x^3-125'
'x'
'2'
returns "-error: No solution? and x:5.265

Thanks for the bug report. Fixed in 0.5.2, posted today. It is broken in 0.6.0 for a different reason (some aspects of the solver are not updated for variable-precision decimals yet).

Quote:2. Request:
Is there any plan for a multi variable single equation solver? The ideal would something like the HP48's ("SOLVR"?) environment. There is a clever implementation in the video below (at around 0:55) where an equation on the stack is saved to the 'EQ' variable and the HP48 enters the SOLVR environment.

Plans, yes. A timeline... not really ;-)

Quote:EDIT:
A solution to the solver problem was quickly posted by c3d on Github.

The problem was wrong defaults for the solver settings.
