Tests 32/64 bits

Fernando Perez
Hi all,

here's the output difference between 32/64 bit tests run:

bic128[scipy]$ diff -u tests_32.txt tests_64.txt

On 32 bits, 869 are found and on Fedora x86_64, it's 863.  Above is
the difference (requested by rkern).

Gotta run...

I think this is fine. The different arises because of extra scalar
types on the 32 bit system that don't show up on the AMD system,
presumably float96 and complex192. Check numpy.sctypes for the
difference.

- complex192 isn't on the 64bit box, but complex256 is, so that keeps
the number of tests for that type equal.

- float96 -> float128, again no change in test count

- for some reason, the 32-bit box gives
 'int': [<type 'numpy.int8'>,
         <type 'numpy.int16'>,
         <type 'numpy.int32'>,
         <type 'numpy.int32'>,
         <type 'numpy.int64'>],

so there's a repeated int32 type listed there.  I don't know what that
means, but obviously it produces extra tests (possibly redundant?)

- Same for uint:

 'uint': [<type 'numpy.uint8'>,
          <type 'numpy.uint16'>,
          <type 'numpy.uint32'>,
          <type 'numpy.uint32'>,
          <type 'numpy.uint64'>]}


In any case, other than this minor difference, current numpy SVN
passes all tests on Fedora8/64bit and Ubuntu Gutsy/32bit.

Cheers,

f

Definitely redundant, but harmless. The code that generates these
lists is numpy/core/numerictypes.py:_set_array_types(). The redundant
ones are dtype('p').type and dtype('P').type. For some reason these do
not compare equal to numpy.{u}int32.
