-In this étude, you will use _regular expressions_ to make sure that input is numeric and to distinguish integers from floating point numbers. You need to do this because +binary_to_float/1+ will not accept a string like +"1812"+ as an argument. If you aren't familiar with regular expressions, there is a short summary in <<APPENDIXB>>.

 The function you will use is the +Regex.match?/2+. It takes a regular expression pattern as its first argument and a string as its second argument. The function returns +true+ if the pattern matches the string, +false+ otherwise. Here are some examples in IEx.
