Display & save floating-point numbers for rules

[thundernixon]

I've noticed that the Rules tab displays rules, but rounds to integers.

In some axes like ital that must be 0–1, this blocks rule functionality.

For example, I assert roman glyph forms when:

• "ital" is 0–0.89 and "slnt" is -7.49–0
• "ital" is 0.09–0

However, this information displays like this:

And if I save it, it overwrites the floating-point values with integers, disrupting functionality.

Unless I'm doing something I shouldn't be doing, this seems like it would be a worthwhile change to make.

Thanks for making another useful tool!

I thought that maybe changing...

...from int() to float() might solve this, but it still rounds values. I'd be curious to learn what causes this issue. 🤔
