Comment:
These give the right answer but also a runtime error:
{{{
sage: floor(x).derivative().subs(x=1.5)
Exception RuntimeError: 'maximum recursion depth exceeded while calling a
Python object' in 'sage.structure.parent.good_as_coerce_domain' ignored
0
sage: ceil(x).derivative().subs(x=1.5)
Exception RuntimeError: 'maximum recursion depth exceeded while calling a
Python object' in 'sage.structure.parent.good_as_coerce_domain' ignored
0
}}}
