Unit conversions with additive factor

We need a way to implement conversions with an additive factors, e.g. Kelvin to Celsius and conversely.

Evaluating an equation with `→Num`

2

When evaluating an equation like `'A*A+B*B=C*C'` with `→Num`, we get a `True` or `False` result. Would it be preferable to see the left and right results?

In an operation like `53000^400`, we first get a `Number too big` error in the integer computation, followed by a decimal result (in that case roughly `5.13272E1889`). We should either...

We get an algebraic where the `6x` part does not render

tests: Occasional corruption of test output

Occasionally, the test output fails with: ``` Summary of 1 failures: ../src/tests.cc:5523: Test #40: rewrites: Equation rewrite engine ../src/tests.cc:5523: 40:028.002: Matching explicit wildcards now works ../src/tests.cc:5523: Expected output ['cos(0·A+A+A)+cos(0·B+B+B+B)+sin(0·C+C+C+C+C)'], got...

We need a function that lists the files on the USB disk.

When using the solver menu, add commands to evaluate the equation value, and to select the next equation if there is a list in `EQ`

Conversion to `knot` or `mph` from `m/s` fails

Saving the state in a new file does not work
