How to convert an integer to a string in Erlang?
I know strings in Erlang can be costly to use. So how do I convert "5"to 5?
Is there anything like io:format("~p",[5]) that would return a formatted string instead of printing to a stream?
Solution 1:
There's also integer_to_list/1, which does exactly what you want, without the ugliness.
Solution 2:
A string is a list:
9> integer_to_list(123).
"123"
