[erlang-questions] binary_to_integer/1 and binary_to_float/1 and friends
Tue May 8 18:35:56 CEST 2012
There is no need to write an EEP for this and we would appreciate a
patch in this area.
For consistency the solution should also have functions called
binary_to_integer/2, integer_to_binary/1,2 and float_to_binary/1 which
behave the same was as their list counterparts.
