How does one convert a CAS symbolic result to numeric (sorta like RPL's ->NUM)?

Example: (CAS Exact setting ON) I was following another thread comparing machine accuracy, and in CAS mode did asin(acos(atan(tan(cos(sin(9)))))which gives a symbolic result (not worth typing here, presumably correct), so I then pressed [a b/c] hoping to see the numeric value but instead get an error, repeating the symbolic result and "Error: Bad Argument Value". No help from eval() either. Shift-Enter produces the same error as well.

I get that I can change the CAS Exact setting and re-enter the equation, but there must be some (obvious?) way to do this, no?
