True, but it requires 3.2+ and does not work correctly for large integers (floating-point runs out of precision long before Python's arbitrary-size integers become unusably large.)

(Of course, this is a silly problem.)

The documentation says it requires 3.2+, but it is working in 2.7 on my Mac, both the 2.7 shipped by Apple and the 2.7 installed by MacPorts.
