Answer 1

This is an ill-defined problem, unless you specify what encoding method you want. And MATLAB does not have an inbuilt function named "float2bin", which is why you are getting this error. This is a topic that has been discussed before on MATLAB Answers, and even some other forums:

Although it is important to note that the problem is ill-defined, because "There is no one right answer on how to represent a fractional number in binary" (quoted from Peter at the last link).
