ERLANG - binary string to integer or float -

i have binary strings in form of either:

<<"5.7778345">> 

or

<<"444555">> 

i not know before hand whether float or integer.

i tried doing check see if integer. not work since binary. , tried converting binary list check if int or float. not success that.

it needs function such as

bintonumber(bin) ->   %%find if int or float   return. 

anyone have idea of how this?

all best

no quick way it. use instead:

bin_to_num(bin) ->     n = binary_to_list(bin),     case string:to_float(n) of         {error,no_float} -> list_to_integer(n);         {f,_rest} -> f     end. 

this should convert binary list (string), try fit in float. when can't done, return integer. otherwise, keep float , return that.
