+    op1 * op2
+
+----------------
+Input parameters
+----------------
+.. list-table::
+
+   * - op1
+     - the multiplicand
+   * - op2
+     - the multiplier
+
+------------------------------------
+Semantics  for scalar operations
+------------------------------------
+The operator addition returns the product of two numbers.
+For example: ::
+
+	3 * 5   gives 15
+
+-----------------------------
+Input parameters type
+-----------------------------
+op1, op2 :: 
+
+	dataset { measure<number> _+ }
+	| component<number>
+	| number
+
+-----------------------------
+Result type
+-----------------------------
+result :: 
+
+	dataset { measure<number> _+ }
+	| component<number>
+	| number
+
+-----------------------------
+Additional Constraints
+-----------------------------
+None.
+
+--------
+Behavior
+--------
+
+The operator has the behaviour of the "Operators applicable on two Scalar Values or Data Sets or Data Set Components" (see the section "Typical behaviours of the ML Operators").
+According to the general rules about data types, the operator can be applied also on sub-types of number, that is the type integer.
+If the type of both operands is integer then the result has type integer.
+If one of the operands is of type number, then the other operand is implicitly cast to number and therefore the result has type number.
