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
