There is a bug, floor() and ceil() are in the wrong table in the expr 
code (the one for 2-arg funcs not the one for 1-arg funcs), or something 
similar.

Try floor($f1, 0) and ceil($f1, 0) (the second argument is ignored).

Should be easy to fix, but would break all patches currently using this 
workaround...
