About functions
A function is a predefined, named formula that performs a specific calculation and returns a single, specific
value.
Most functions include three basic parts:
1 the function
1 a set of parentheses, if the function takes parameters
1 the parameters required by the function
Each function returns a result of field type text, number, date, time, timestamp, or container.
FileMaker

Using this functions reference
The content in this document was originally written for the FileMaker Pro and FileMaker Pro Advanced
Help. It has been collected in this format to allow solution developers to read the information independent
of the help system.
The following chapters present the functions by category. FileMaker Pro functions are grouped by the type
of data they operate on, not by the type of data they return. For example, the Position function returns a
number, but it is grouped with Text functions because it operates on text data.
