Not exactly efficient, but it works (pay attention to the spaces is
round(), `expr` is especially picky...)::

  $ floor () { echo "$1" | sed -e 's|\.[0-9]\+||'; }
  $ floor 0.1
  0
  $ floor 10.89
  10

  $ ceil () { expr $(floor "$1") + 1; }
  $ ceil 0.1
  1
  $ ceil 10.89
  11

  $ round () { expr $(echo "$1" | sed -e
's|\.[0-4][0-9]*||;s|\.[5-9][0-9]*| + 1|;'); }
  $ round 10.89
  11
  $ round 0.1
  0
