Is there a size limit for Erlang integers?

I know that Erlang has arbitrary dimensional numbers, but is there a maximum limit on one of the standard implementations? If yes, then?

Erlang uses bignum arithmetic , and integers in Erlang are limited by the available memory on the machine. In fact, there is no limit to how big Integer is in Erlang. Take a look at this document: http://erlang.org/doc/efficiency_guide/advanced.html It contains more detailed explanations regarding the limits.
