Is *anything* used for this, outside of the TI-83 and TI-84 machines, other than an ordinary minus sign or hyphen-minus?

There are actual mathematics experts on this list, but my understanding is that normal mathematical notation—as used both by experts and the general public—uses the same symbol for both unary and binary minus. The TI calculators may have distinguished between the two to make input or internal parsing easier.
