Number Type
A real number, i.e. 1, -25, 6.52, 1805.6352
Numbers are stored as single precision floating point numbers, which allow for a large range of values with limited precision (generally accurate to 6 or 7 decimal places).
The largest real positive number that can be entered via script is: 3.4028235e38
The largest real negative number that can be entered via script is: -3.4028235e38
Larger numbers: In scripts it is possible to generate a representation of an infinite positive or negative number which compares even larger or smaller than the above two floating point limits;
Positive infinity 1e39 = "1.#INF"
Negative infinity -1e39 = "-1.#INF"
Indeterminate (NaN) = "-1.#IND"
The finite command can be used to verify if a number represents infinity or NaN.
Degrees
Degrees are a poetic licence used to indicate a number returned from functions like acos and asin
It's special properties are that it will always supply a value from 0 to 360
Radians
Another poetic licence for a Number. Used in angular math computations with commands like rad and deg
Scripting vs Addons
Integers and Floats
Note that unlike config.cpp's (addons), a Number in scripting language is ANY numeric entity. Floats, or integers. It is NOT the same as a config's Integer or Float. Number covers both types.
Booleans
Note also, unlike config.cpp's, Boolean is a real type in scripting language. In addons, it is a poetic licence for a zero/non zero Integer
