title: SQL Return Monthly instead of Annual Salary & Round to 2 decimal places
body: <p>I've been learning SQL in microsoft visual 2015 for the past 4 days and slowly getting used to it, My teacher gave me this homework to solve and im part way threw but now im stuck its a simple Query 
  I basically have to bring the Annual salaries up in the table and instead of showing them as annual salaries i need to show them by monthly so (abit of maths to divide them) i also need to round to 2 decimal places.. Here is the question along with my Query </p>
  
  <blockquote>
    <p>List the last name of all employees in departments 50 and 90 together with their
    monthly salaries (rounded to 2 decimal places), sorted in ascending order of last
    name</p>
  </blockquote>
  
  <pre><code>SELECT Last_Name, Department_No, Annual_Salary AS 'Monthly_Salary'
  FROM Employees
  WHERE Department_No = 50 or Department_No = 90
  ORDER BY Last_Name ASC
  </code></pre>
  
  <p>That works fine I just have to idea how to show the Annual_Salary as a Monthly one nor how to round to 2 decimal places.
  Thank you for anyone who can point out the answer and explain a little to me :)
  Kind Regards!</p>
