Yes and 0! It took all of about 15 seconds to test:

$ nroff << END
.nr a 1
.nr 1t 2
this is the value of a: \na and this is the value of b: \nb. Did you see
it?
and this is the value of 1t: \n[1t]
END

produces

this  is the value of a: 1 and this is the value of b: 0. Did you
see it?  and this is the value of 1t: 2
