floor should not do anything different in the teaching languages than 
in full scheme. If floor receives an inexact number, it produces an 
inexact and if it receives an exact, it produces an exact. The 
difference you might be seeing is that decimal constants are treated 
as exact numbers in the teaching languages, but they are treated as 
inexact numbers in the full languages.
