The question is clear enough.  What I'm unclear about is what you found
unclear in the docs for the int() function:

    http://www.python.org/doc/current/lib/built-in-funcs.html

and in particular what about

    Conversion of floating point numbers to integers truncates
    (towards zero)

did you read as leaving the question open?
