Oracle9i OLAP Services Developer's Guide to the Oracle OLAP API Release 1 (9.0.1) Part Number A8875601 

Performing Calculations, 4 of 7
The OLAP API has many methods that represent standard numerical functions. When you use these functions with a NumberSource
, they return a new NumberSource
that has the same structure as the original NumberSource
and whose elements have the values of the original NumberSource
modified according to the function. For example, the abs()
method returns a new NumberSource
each of whose elements has the absolute value of the value of the corresponding element in the original NumberSource
.
You can also write your own functions as described in "Creating Your own Numerical Functions".
The OLAP API methods that represent standard functions include those listed in the following table.
For a more complete explanation of these methods, see Oracle OLAP API Reference.
