+Subject: [PATCH] Fix the comparison in test_compatibility for NumPy 2.0.0
+
+The comparison in `mpmath/tests/test_convert.py::test_compatibility`
+failed for `np.float16` in NumPy 2.0.0 since `2.0**-53` cannot be
+represented in half-precision floating point type.  Convert the LHS
+to `np.float64` to ensure that the comparison is done in sufficiently
+precise type.
+
+This fixes the actual test failure from #815 but the deprecation warning
+remains.
