[GiNaC-list] how to drop terms in expression with small coefficients?

I have the following problem - I have a polynomial P(x) and before I
proceed with some calculations on it, I want to make sure it does not
contain terms like for example:
10e-12 * x
(in my case x is from (0, 1) so this is safe).
I want to somehow get rid of such small terms.
In another words for polynomial P(x) = 2.3 * x ^ 2 + 10e-12 * x + 3.76
I want to obtain polynomial Q(x) = 2.3 * x ^ 2 + 3.76
How do I do that i GiNaC?
I will kindly appreciate any advice.
