When using expressions the four data types may be encountered:
1. Number
In expressions numbers are often used for calculations (addition, subtraction, multiplication, and division). These can be whole numbers (integers) or decimal numbers (floats), and can be positive or negative.
2. String
A string is a sequence of characters, such as letters, numbers, symbols, and spaces, that is enclosed in quotation marks. When using expressions, strings are often used to represent text, such as labels, list of values, etc. They can be combined using concatenation to create longer strings. Numeric value can be displayed as a string but has to be explicitly converted.
3. Multistring
A multistring is a list of strings such as ("string1", "string2", "string3"). If needed multistring can be converted to a single value by using functions such as ItemAt or Join.
4. Boolean
A Boolean value is either true or false. When using expressions, Boolean values are used to represent conditions, such as whether a certain value is greater than another value or whether a certain text contains a specific substring.
5. Table
A table which format includes the following columns: id, label and value. Tables can be filtered, sorted, and combined using various functions.
