BinaryOperation: MDCalculationFormulaBinaryOperation;
The BinaryOperation property determines a form of binary opposition used as a formula operand.
Executing the example requires that the repository contains multidimensional calculation on database server with the MDCalc_1 identifier.

After executing the example the formula is set for the element that corresponds to the first elements of data consumer slices. The value by coordinate in the data consumer is calculated by the formula: value by coordinate in the data source multiplied by 3.14.
