TI-84 CE-T (v5.4.0.0034)
returns an error
tan(pi/2) = Error

I'd prefer an error over the misleading answer that is the result of underlying approximations.
My guess is that TI and other calculators recognize the special condition and bypass the approximate calculation and issue a predefined result.

(I'm not into CAS as of yet)
