- Method Detail
  - abs
```
ServerExpression abs(ServerExpression arg)
```
    Returns the absolute value of arg. If arg is negative returns -arg otherwise returns arg. If type of arg is one of the four numeric types xs:float, xs:double, xs:decimal or xs:integer the type of the result is the same as the type of arg. If the type of arg is a type derived from one of the numeric types, the result is an instance of the base numeric type.
    Provides a client interface to the fn:abs server function.
    
    Parameters:
    
    arg - A numeric value. (of xs:numeric)
    
    Returns:

```
ServerExpression deepEqual(ServerExpression parameter1,

    This function assesses whether two sequences are deep-equal to each other. To be deep-equal, they must contain items that are pairwise deep-equal; and for two items to be deep-equal, they must either be atomic values that compare equal, or nodes of the same kind, with the same name, whose children are deep-equal. This is defined in more detail below. The collation argument identifies a collation which is used at all levels of recursion when strings are compared (but not when names are compared), according to the rules in 7.3.1 Collations.
