How to concatenate list of integers into a single number

$begingroup$
Is there a way to concatenate the elements of a list 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.

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 *)
