hi every1, I got the following issue: I wrote a function that converts binary strings into a decimal value (binary expansion). When I write type(x) to find out the type of the value I get NoneType. Therefore I can't convert it into anything else, such as float numbers, since command float(x) returns TypeError: float() argument must be a string or a number Any ideas what to do with this (e.g. convert to floating numbers)? cheers, Alex
