Bug#669967: say what happens when a non-integer is passed to chr

       chr NUMBER
       chr Returns the character represented by that NUMBER in the character
           set.  For example, "chr(65)" is "A" in either ASCII or Unicode, and
           chr(0x263a) is a Unicode smiley face.

OK, but what about chr(65.99)? Say something (document) what about if a
non-integer is passed to it.
