Numbers

Numbers are either integers or floating point numbers in the following notation:

42

-13.42

Important to note for floating point numbers is that they must always be specified in English notation with "." as decimal separator and without thousands separator when they appear directly in a TL script expression. In outputs and inputs, however, numbers can of course be formatted with the conventions of the user's language, see Number Format.

Truth values

true

The literal for the truth value "true".

false

The literal for the truth value "false".

Strings

The expressions "some string" and 'some other string' represent the literal string values some string and some other string, respectively.

Note: In an internationalized application, a string should not be used directly to communicate with the user. Internationalized texts should be used instead.

No value

null

The literal for the empty/undefined value "null".
