Intrinsic Functions
The table below shows all available intrinsic functions.
The Function name column defines the name of the function.
The Function type column defines the type of the function, it can be: Integer, Numeric, Alphabetic, Alphanumeric. When "any" word appears it means that the type of the function depends on the argument type.
The Argument number column defines the number of the arguments. When "arbitrary" word appears it means that the number or arguments is undefined and it can be arbitrary. When 0 appears, it means that the function doesn't has arguments.
The Argument type column defines the type of the arguments, they can be: Integer, Numeric, Alphabetic, Alphanumeric. When "any" appears it means that the type of the argument can be any of theme.
A detailed documentation of each single function follows.
