Stlsort does not correct "negative zeros" (-0) about stlsort HOT 4 OPEN

The evolved version of my utility, which I think this is based on, has a fix for negative 0. https://github.com/nophead/NopSCADlib/blob/master/scripts/c14n_stl.py#L35

Hey Roman. Thanks for the report. stlsort currently:

1. converts the values to Python floats but preserves the original values
2. sorts the data using the float values
3. outputs the original values

This means that if the original file has 1, it will still have 1, while if the original file has 1.000 or 1e0, that literal value will be used.

I think that converting -0 to 0 but preserving all other values is not very systematic.

stsort could convert the values to a canonical form, but it would need to be well-defined and optional (e.g. via a command line switch), to preserve backwards compatibility.

I can definitively review such addition, but I won't be implementing it myself. The current functionality of stlsort works nicely for my needs.

You are correct, this is based on your utility.

Thanks for the summary and brief description of the function. I'll try to use the tool from @nophead (NopSCADlib) and if that's not enough, I'll try to create some argument to stlsort. (Or do you want this feature in STLSORT?)

I will close the issue when I find a solution to this problem.
