The following table lists only the categories of X++ functions. Each category is described. These categories help people to understand the many functions, but the categories do not represent any formal construct in Microsoft Dynamics AX.
Functions that input financial data and calculate formulas.
(also named Intrinsic)
Functions that have their input value verified by the compiler. If the input value is not found to match any existing object in the Application Object Tree (AOT), the compiler issues an error.
The inputs to these functions must be literals, because the compiler cannot determine the value that a variable contains at run time.
Functions that operate on the container data type of X++.
Functions that translate data of one type into data of another type.
Functions that operate on the date data type.
Functions that operate on enum objects.
Functions that perform mathematical calculations.
Functions that do not belong to any specific category.
Functions that access the metadata about objects and return other metadata about them.
Functions that change or report on the context of the current user connection.
