`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.
