Of course, arithmetical functions like +, * and so
forth, have been reused for enhanced number types. These are
transparently overlaid. This concept allows to use the same emacs
lisp code for both non-ENT and ENT-SXEmacsen.
However, some of the arithmetical changes are not intuitive, so we discuss them here. Please always refer to Numbers for function and variable equivalents in a non-ENT-SXEmacs.
