You betcha; the 80x87 and the 6888x implement everything including the
kitchen sink, notably the trig functions. Never mind the mundane stuff
like cos(): the 68881 has a hyperbolic-arctangent instruction!
Of course, the newer and faster FPUs like the MIPS one don't have all
this gingerbread, so who knows what next year's FPUs will look like...
