assert_that(float("nan")).is_close_to() passes when comparing with numeric values #155

Description

When using assertpy’s is_close_to() assertion, comparing float("nan") to a numeric value unexpectedly passes.


Steps to reproduce

from assertpy import assert_that

assert_that(float("nan")).is_close_to(123, 0.1)

Expected Behavior:

The assertion should fail, since NaN is not close to any number (including itself).


Actual Behavior:

The assertion passes without error.
