No, there will be a Python int created and I don't think it is possible
to skip this in Python.

Well, Cython gave you what you asked for :-)

Hello,
How do we convert Python object to a C long in Cython? The following

What can be done ?

0" ?
A human will handle factorization and get the answer : x = 0 or tan x =

I bet I know why : we can trick mathematical sofware in various
ways,...,but why should we ?
find_root is "numerical" function to get approximate real root of function
in intervalwhen we know ( "theorically") the root exists !!
the function can be implemented in various ways, and for example
