Here's a hack that lets one do "calc 2/3" and get a floating point
answer.

calc () {
        setopt localoptions extendedglob
        local expr="$*"
        if [[ "$expr" != *.* && "$expr" = *(#b)([0-9]##)(#B)' '#/' '#([0-9]##)* ]]
        then
                expr="${expr/${match[1]}/${match[1]}.0}" 
        fi
        print $(( $expr ))
}
