How to extract elements of a list and append?
$begingroup$
A beginner's question:
Is there a way to extract elements of a list and append them into ONE number?
For example, if there is a list L={13,5,8,0}
, then I am looking for a way to append 13
, 5
, 8
and 0
to produce the result 13580
.

Or FromDigits:
FromDigits[{13, 5, 8, 0}]

(+1) you will need something likeFromDigits[Flatten@IntegerDigits@L]
to cover cases likeL={1, 13, 5, 8, 0}
.

You can convert the list numbers to strings, then join and finally convert back to number:
L = {13, 5, 8, 0};
ToExpression[StringJoin[ToString /@ L]]
(* 13580 *)

FromDigits @ StringJoin @ IntegerString @ L

FromDigits @ StringJoin @ IntegerString @ {13, 5, 38, 13}
