Only ints return from SQLite queries with calculations

Question

Howdy.  Hope I have the right forum for this question.
I'm on a project using a SQLite database in Flex 4 and I'm using the following SQL query:
SELECT max(totalScore) AS score,
               max(longestStreak) AS streakLen,
               max((correctNotes * 100) / totalNotes) AS accuracyPercent
FROM main.practiceRecord rec
JOIN main.lessonSession sess
ON rec.sessionGuid = sess.guid
WHERE sess.purchasedLessonID = :lessonId
The query is working fine as it is written.  The problem is that when I do the calculation ((correctNotes * 100) / totalNotes) to return a percent value, I'd like to do it without having to multiply by 100, since I generally treat percentages as numbers between 0 and 1 (.68 = 68%).  If I don't multiple by 100 in the query, however, I get a "0" for anything less than 1, so only 100% returns with the correct value.  It appears that this kind of calculation only returns an int, as opposed to a REAL (or its AS3 corresponding "Number").
Is there something that I can do to return a value between 0 and 1 for this percentage so that I don't have to multiply by 100 in the query and then divide by 100 when I get the result?  Is there a function that allows me to specify the precision for the returned value?
Thanks for your time,
Bryan

Maybe Tom Kyte's "trick" of the "select pl_sql_function () from dual" to invoke scalar subquery caching can help you:
select ename
  from emp, dept
where (select dname_lookup(emp.deptno) from dual) = 'SALES'
   and dept.deptno = 30
   and emp.deptno = dept.deptno;http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1547006324238
As Tom says, in 11g you'll be able to cache that function (new 11g feature) which removes the need for the "trick":
