Issue type: Bug
Clarity: Mostly clear
Activity status: Stale
Tech stack: numpy
Domain: testing

Research direction

Start with array_api_tests/test_creation_functions.py::test_linspace and reproduce the falsifying example using num=1, dtype=numpy.float32, endpoint=False, start=-0.0, and stop=-1.0. Read the linked linspace specification to determine whether preserving negative zero is required; done means the test behavior and expectation match the specification.

Written by the indexing model from the issue text.

Description

FAILED array_api_tests/test_creation_functions.py::test_linspace - AssertionError: out[0]=0.0, should be -0.0 [linspace()]
Falsifying example: test_linspace(
    num=1,
    dtype=numpy.float32,
    endpoint=False,
    data=data(...),
)
Draw 1 (start): -0.0
Draw 2 (stop): -1.0
Draw 3 (kw): {'dtype': numpy.float32, 'endpoint': False}

Not clear if this is actually required by the spec or not. See https://data-apis.org/array-api/latest/API_specification/generated/array_api.linspace.html
