Introduction
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
®
 Pro provides many functions for you to use in your FileMaker database solutions. 
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 
 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.
