It behaves exactly as documented (Library Ref. 2.1): "If the argument is
a string, it must contain a possibly signed decimal number representable
as a Python integer...". Basically, it is only doing a one-step
conversion (whereas "3.14" -> 3.14 -> 3 would be a two-step conversion).
You can easily get the functionality you expect by:

  x = int(float('3.14'))
