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:
• the function
• a set of parentheses, if the function takes parameters
• the parameters required by the function
Each function returns a result of field type text, number, date, time, timestamp, or container.
For information about where functions can be used, see About formulas.
Parameters
Function parameters can be constants (such as 1.07 or “hello”), field references (such as
InvoiceTotal), expressions (such as 1 + 12), or other functions (such as the NPV function). You can
use spaces before or after the parentheses used to enclose the parameters, but spaces are not
necessary. When a function requires more than one parameter, separate individual parameters with
a
list separator, such as a semicolon.
Important See Design functions for information about literal text parameters.
Curly braces ({ }) surround optional parameters (for example, the Case function and Choose
function). An ellipsis (...) signifies that you can add more parameters, each separated by a
semicolon (for example, in aggregate functions). Double quotation marks (“ ”) indicate a text string.
