AssertionError:
Arrays are not almost equal to 30 decimals

Thirty decimals? What architecture?


`decimal=30` is used in three places in numpy/core/tests/test_blasdot.py, in the function `test_dot_array_order()`.  It looks like the argument should be `decimal=prec`.

If I make that change, the above test passes, but I get a failure in a test for array equality in the same function (lines 119-120):

            a_T = a.T.copy(order=a_order)
            assert_array_equal(a_T.dot(a_T), a.T.dot(a.T))


When the dtype of `a` is float32, this test fails.

I'll guess it's the ancient version of gcc.
