Out of interest, what should the calculations 90D 1 + and 1 90D + give in radian mode? On my calculator, 90D 1 + gives 147D and 1 90D + gives 2.57R. In each case, the "1" is treated as 1 radian and the tag for the answer is taken from the first argument. I agree that other approaches can make sense; however, I think it is very desirable that addition should remain commutative. In degrees mode your suggested logic respects this  91D and 91 are the same quantity, so far as trig functions are concerned. So long as the same is true in radian mode, I'll be content. Nigel (UK)
