In every ESL statement in which a value is required, you must specify a value of a particular type, or use the default value. The following table lists the different types of possible values, system defaults (where applicable), and examples of each type.

Description
Every value you specify must match the type required in the particular syntax model. Throughout this guide, syntax models indicate the type of value required in each statement. If you specify a value of the wrong type, ESL converts the value if it can. (See Type Conversions.)
Built-in functions do not return floating point values.
