Sure you could:

NUM=${1:?"Usage: $0 number"}
INT=${NUM%%.*}

if expr ${NUM} : "[0-9]*.[0-9]*" >/dev/null; then
        REM=${NUM##*.}

        if [ ${REM} -gt 0 ]; then
                INT=$(( ${INT} + 1 ))
        fi
fi

echo "Rounding ${NUM} yields ${INT}."

Using decimals is perfectly fine, too.
