Setup

var abc = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, '0', '1', '2', '3', '4', '5', '6', '7', '8', '9'], result = 0;
    function num(e,i,o){
        var t = Number(e);
        if(!isNaN(t))
            result += t;
    }
    function pai(e,i,o){
        var t = parseInt(e);
        if(!isNaN(t))
            result += t;
    }
    function paf(e,i,o){
        var t = parseFloat(e);
        if(!isNaN(t))
            result += t;
    }
    function imp(e,i,o){
        var t = +e;
        if(!isNaN(t))
            result += t;
    }
    function bor(e,i,o){
        result += 0|e;
    }
    function bxo(e,i,o){
        result += 0^e;
    }
    function bno(e,i,o){
        result += ~~e;
    }
    function ble(e,i,o){
        result += e<<0;
    }
    function bri(e,i,o){
        result += e>>0;
    }
    function bbr(e,i,o){
        result += e>>>0;
    }
