Title: 0.4rc1: test_Rotation2D_inverse failure on powerpc and s390x

On Debian/Powerpc and Debian/s390x, the 0.4rc1 version fails with
```
def test_Rotation2D_inverse():
model = models.Rotation2D(angle=234.23494)
inverse = model.inverse()
x, y = inverse(*model(1, 0))
> utils.assert_allclose([x, y], [1, 0])
