Copilot Summary
This pull request adds support for the
heavisidefunction to the QuadPrecision dtype, implementing both the core logic and comprehensive tests. The implementation follows NumPy's behavior, including correct handling of NaN propagation and broadcasting. Documentation and release tracking have also been updated to reflect this new feature.Implementation of
heavisidefunction:quad_heavisideandld_heavisidefunctions implementing the Heaviside step logic for quad and long double types, with correct NaN propagation and handling for all edge cases. [1] [2]heavisideufunc for QuadPrecision by updating the binary ops initialization.Testing:
np.heavisidewith QuadPrecision, covering basic, edge, special, and broadcasting cases to ensure correctness and compatibility with NumPy's semantics.Documentation and tracking:
