Convert an Character to the ASCII Character Code

[John Gregory]

I have Ruby 1.9.1p129 and I want to convert an ASCII character to an
Integer and a Float.

While reading the following web page, I found conflicts in the code
usage:

'Convert an Character to the ASCII Character Code'

Integer (?e)
=> 101

(then further down)

Float (?e)
=> 101.0

I received errors as per the attached screen snapshot.

I have found out that it is because I have version 1.9 and the above was
only workable in version 1.8.

I would still like to know how to get the same results using my current
version.

Thanks.
