decimal value bug, but it's predicated on the assumption that we don't let shifts
be non-integer values.  This is an OK assumption for now, but may bite us
in the ass someday.  

A solution might be to subtract just the part in front of the decimal point, and do some if statements on what range that falls into... 
sprintf("%d") or sprintf("%0f") is likely the key....
