Constants

Constants are static values that are set in the expression.


String	A text value. This value is represented by the color Blue.
Integer	A numerical value with no decimals. This value is represented by the color Green.
Time	A time in the HH:MM:SS format.
Date	A date in the YYYY-MM-DD format.

Note: When creating Expressions, ensure the correct data type is being evaluated by selecting either String or Integer from the drop-down menu. If left on Default, the platform will attempt to infer the type automatically. However, mismatched types may be auto-converted, which can lead to unexpected results. For example:

Integer + String (numeric) → The String is converted.

Ex: 1 (int) + "1" (string) = 2.
String + Integer → The Integer is converted.

Ex: "1" (string) + 1 (int) = "11".
