I think "a in RR" is what you want to use. Your first attempt could work too, using a try/except block.
For testing integrality, or rationality, "in ZZ" and "in QQ" work similarly.
And if you know the numbers you're checking are complex, you could also test to see whether their imaginary parts are zero.
