Real coefficients in complex numbers

If you are calculations with complex numbers: a + I b How do you state
that a and b are real? For example I might want to calculate the real
part of

a + 1/(b + 1/(1/I c + d)) ; Where a,b,c,d are real

Can this be done in a nice way. (Yes, I do know how to do the
calculation by hand)
