Numbers are a means to add some programmatic functionality to Sword of Moonlight via calculator like mathematical expressions. Numbers are typically setup inside of an Ex.ini file. This list contains built in and so-called system numbers only.

Serialization

It is possible to write a series of numbers. Care must be taken to not do so accidentally. The following table demonstrates the rules that must be followed. However the basic rules are pretty simple. If a mathematical operator has a space on one side, then it must have a space on its other side, and vice versa. In other words, 1 + 2 or 1+2. If a positive (+) or negative (-) sign appears in front of a number it must be flush with the number, or -1, not - 1. There are no operators that appear behind numbers.

input produces output
1+ 2 => #nan
2 +3 => 2, 3
3 + 4 => 3+4
4 + -5 => 4-5
input produces output
5 +-6 => 5, -6
-6+7 => -6+7
-7--8 => -7+8
-8 --9 => -8, 9


If you experience different results then that is a software bug that should not be relied upon in order to ensure you expressions continue to work correctly in the future.

Empty spaces and separators

Spacing characters include space ( ), tab, carriage-return, new-line, and any other character that produces empty space wherever it appears. Note that tab and other kinds of characters sometimes appear as zero width spaces. This can be a nuisance as they will still be considered a space nonetheless.

End of the line characters (carriage-return and new-line) are ignored along with any spacing characters that follow. When working with multiple lines care must be taken to observe spacing rules precisely. When a series is spread over multiple lines an explicit separator (#,;) should be placed between the last element on the line and the first element on the next line. A semicolon (;) at the end of the line is recommended for this.

,;

The colon (,) and semicolon (;) are reserved separators. They are strictly equivalent to a space ( ) character, except you can see them as written. In other words 1 2 or 1,2 or 1;2 it doesn't matter. If necessary more separators can be added or an extension can be provided to allow for the definition of custom separators.

Note that separators are simply filtered out. So if you write 1,+,2 this is equivalent to 1+2. Care should still be taken to observe the rules of serialization and cautions about working with multiple lines in the previous section.
