Power Fx formula reference for Power Apps
Formulas combine many elements. Listed below are:
- Functions take parameters, perform an operation, and return a value. For example, Sqrt(25) returns 5. Functions are modeled after Microsoft Excel functions. Some functions have side effects, such as SubmitForm, which are appropriate only in a behavior formula such as Button.OnSelect.
- Signals return information about the environment. For example, Location returns the device's current GPS coordinates. Signals don't take parameters or have side effects.
- Enumerations return a pre-defined constant value. For example, Color is an enumeration that has pre-defined values for Color.Red, Color.Blue, and so forth. Common enumerations are included here; function-specific enumerations are described with the function.
- Named operators, such as ThisItem and Self, provide access to information from within a container.
