Here's a link to a typical circuit:

By definition, a BCD to 7 segment display only provides for displaying 0-9 on the display, so to show a minus sign requires additional circuitry (not shown on any site I've seen so far) to drive segment 'g'. The good news is that the decimal point does have its own pin so that can be controlled separately (again, by additional circuitry).
