If you create a constant Poly, it picks the domain. You should look at
the source to see how it picks that.

But you can't create a constant Poly without giving the domain. Try
something like the following (and, again, trace the code to see if there is
a more direct way of learning the domain):
Poly(1.2+var('x'))
Poly(1.0*x + 1.2, x, domain='RR')
Poly(1+var('x'))
Poly(x + 1, x, domain='ZZ')
You can't create it without giving a variable, but you can easily do
Poly(1, x).get_domain(). There's probably a more direct way, though.

I think we can make regular expressions that will match Integers, floating
points etc. Something along the lines of this
for int - re.compile('^\d+$')
for float - re.compile('^\d+\.\d+$')
What do you think about it?

First, it' unnecessarily slow.
I think that makes sense. I think this functionality is already implemented
in Polys module in some form. I am not able to pin point it.

Just check whether f == round(f) for floats.
Second, the question whether a float is integral or not borders on
Hello.
I do not know if it is the case but I think that sympy should have a domain
method for expressions. This will avoid error like for example float
calculations raising to 1 for example that wi-ould not be a natural but a
float.
