What symbolic system are your trying to use? Built-in objects in Mathematica have names beginning with upper-case letters; function calls surround their arguments with square-brackets, not parentheses. In any case, I don't see any "s" in the output. The relevant Mathematica function is -- guess what! -- Floor to calculate the floor of something. Of course you cannot expect it to do an actual evaluation of the Floor of something unless all the variables inside the argument already have actual numeric values.
