A good function to help to find if a number is odd or pair.



function is_odd($tmpnumber){



        if ($tmpnumber < '0') $tmpnumber = gmp_mod($tmpnumber);

        if ($tmpnumber == '0') return(false);

        elseif ($tmpnumber == '1') return(true);

        elseif ($tmpnumber > '1'){

    if (gmp_div_q($tmpnumber,'2') != '0') return(true);

    else return(false);

    }

}
