Additional NewtonScript Features
Other Standard Types
Beyond frames, arrays, and symbols, NewtonScript also provides some other essential types. These are integers, reals, characters, and booleans. Here is a brief description of each:
- Integer
- A 30-bit integer that can hold values from -229 to 229-1.
- Real
- A 64-bit floating point number.
- Boolean
- There are two boolean constants,
true and nil. In boolean expressions, any non-nil value is considered true. Note: the integer 0 is not the same as the boolean nil.
- Character
- A character. Character constants begin with a
$ (e.g., $a, $b, $c). These are 16-bit characters that use the Unicode encoding scheme.
Strings, another NewtonScript type, require some additional discussion.
