+

+
+

+
+Bin :: binary()
+Int :: integer()
+
+

Validate and convert the text representation of an integer.

+
+
int(reverse, Int) -> {ok, Bin} | {error, not_an_integer}
+
+

Convert an integer back to its text representation.

+
+
int(format_error, Error) -> HumanReadable

+Error         :: {not_an_integer, Bin | Int}
+HumanReadable :: iolist()
+
+
