Plus Minus

    Here is a PHP version. $arr is the input array.

    `$res = array_reduce($`arr, function(`$carry, $`val) {(`$val>0)?$`carry[0]++:((`$val<0)?$`carry[1]++:`$carry[2]++); return $`carry;},[]);    

printf ("%f\n%f\n%f", `$res[0]/$`n, `$res[1]/$`n, `$res[2]/$`n);

      pretty cool!, a little more readable for me:

      $res = array_reduce($arr, function($carry, $val) {

      ($val>0 and carry[0]++) or ($val<0 and $carry[1]++) or (!val and $carry[2]++); return $carry;},[]);

      printf ("%f\n%f\n%f", $res[0]/$n, $res[1]/$n, `$res[2]/$``n);
