This looks good, but, I noticed:

> Supported Functions (v1) > SUM, AVERAGE, COUNT, MIN, MAX, IF

I would recommend switching to numerically stable algorithms for adding numbers and taking their averages sooner rather than later.

Looking at the code[1], it looks like you are simply summing the numbers and dividing by count. If that is indeed the case, please switch to a stable average[2]. See also [3].

Additionally, I tried to test the executable[4] on Windows, but there is something wrong with input. Using Windows Terminal Version: 1.24.10921.0, characters are doubled on input. Regular Vim compiled using Visual C++ does not have this issue.

When I press `:`, I get `::` in the COMMAND line. Then, every key I press gets doubled. This means I cannot `:q!`. :-)

This is valuable feedback. I opened two issues to track this:

Use numerically stable algorithms for SUM and AVERAGE: https://github.com/garritfra/cell/issues/43

Keystrokes doubled in Windows Terminal: https://github.com/garritfra/cell/issues/44

Thanks!
