Re: On trits & tetrits...
Dan,
At first glance, I like the idea. In particular, setting
inDomain(sqrt,[-1,1]) = {true,false} reflects accurately that there
are points in [-1,1] that are in the domain and points that
are outside of the domain, so it is a well-defined set-to-set
mapping. Also, if one is thinking of [-1,1] as representing
a single number that is only known to lie within that interval,
one can still interpret the set {true,false} as representing
"possibly in domain".
