Task Write a npv named deterministic function that calculates the Net Present Value (NPV). It should accept the following parameters: A future_value parameter using a number data type. A periods parameter using an integer data type. An interest parameter using a number data type. The npv function should return a decimal (in Oracle a NUMBER data type) value rounded to the nearest penny. Replace the < < >> placeholders with functional code. CREATE OR REPLACE FUNCTION npv ( future_value NUMBER INTEGER NUMBER) RETURN NUMBER DETERMINISTIC IS BEGIN , periods , interest RETURN < < >>; END; Test Case: Write an anonymous block program that calls the npv deterministic function you wrote and prints the results. Replace the < < >> placeholders with functional code. SET SERVEROUTPUT ON SIZE UNLIMITED BEGIN /* Call, round, and print the return value from the npv deterministic function. */ < < >> END; / Put your script that creates the function and tests the function in the answer for this lab.
