Ok, simple question, but not the expected simple answer:

limit(sqrt(x-4), x, 4)    'sqrt' bieng the square root symbol

    My TI-92 (ROM 1.11) evaluates this limit to be zero.  However this
should only be correct if evaluating from positive infinity down to 4.
It ought to give back the result of undefined since it was told to
evaluate from both sides.  Also, zero is returned even if it is told to
evaluate from negative infinity up to 4.
    Could someone who has ROM 1.12 try this and confirm the answer, and
also someone who knows what the real answer should be (it's been a long
time since I've had a course with limits).

Thanks!  (sorry for the off-topic post, I'm just curious)
