Also, some checks are pretty adhoc (e.g using struct module to check for 64-bitness). This change bases entire detection on sys.maxsize and integer operarions, and thus more correct, even if longer. Note that this change doesn't mean that any of these tests can pass with anything but MPZ - even despite checking for various int representations, the tests aren't written to be portable among them. test/float2int: Make test output clearer. 2016-02-13T15:03:02+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-02-13T14:52:08+00:00 urn:sha1:dc587a362351ae8d56baf16a91d13d75c5cd62a4 modstruct: Rename module to "ustruct", to allow full Python-level impl. 2015-05-04T13:53:52+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-05-04T13:35:40+00:00 urn:sha1:3d3ef36e977b5f5a4153b8df6447f3f73e4726e3 tests: Update float2int tests for new range classifications 2015-01-24T21:05:16+00:00 David Steinberg david.steinberg.dev@gmail.com 2015-01-23T17:52:22+00:00 urn:sha1:4c1a7e0d6a561be5871bb0d36b724f529e55c21d - Tests vary based on build configuration (32/64-bit and internal int type). - Added tests for exceptions raised on overflow of int type. py: Temporary fix for conversion of float to int when fits in small int. 2015-01-07T12:10:47+00:00 Damien George damien.p.george@gmail.com 2015-01-07T12:10:47+00:00 urn:sha1:ad2307c92c15f0aa90dbd0741fd2538719d0b5e1 Addresses issue #1044 (see also #1040).

This is for example the case of 32-bit platform using doubles, and converting value of time.time(). Conversion of floats with larg exponnet is still not handled correctly.
