Define positive and non-null number field types

[aababilov]

They are already used in the table descriptions.

Sounds good to me!

If you want to be exhaustive with this PR, "Float" alone should be also defined as it is used for levels.level_index and pathways.max_slope.

I'm wondering if we could separate Field Types from their factors as to avoid exhaustively defining every factor combination of integer and float (and potentially currency amount). Also, "Non-null" could be interpreted as "not empty". I think the intended meaning is "Non-zero". Something like:

Field Types

• ...
• Float - A floating point number.
• Integer - An integer.
• ...

Field Factors

Factors applicable to Float or Integer field types:

• Non-zero - Non-zero.
• Non-negative - Greater than or equal to zero.
• Positive - Greater than zero.

I like the idea!
However, each field type and field factor should have a precise definition (e.g: "Non-zero - Non-zero" is not a precise definition).

@timMillet @aababilov Please see the PR I made (aababilov#1) containing my revised suggestion as outlined in my previous comment. If it does not address the need, feedback for improvement is welcomed!

[aababilov]

Updated. PTAL.

[timMillet]

All good for me!

@aababilov @timMillet I forgot a detail. As Field Signs is a new heading, I suggest to add it to the TOC. See my PR here. Thoughts?
