For example, when rounding the number -1357.1357 to negative 4 decimal places, the function returns -0.0 instead of the expected 0.0.\n\n**Steps to Reproduce:**\n1. Open a Python interpreter.\n2. Execute the following code:\n\n```\nprint(round(-1357.1357, -4))\n```\n\n3. Observe the output.\n\nExpected Result: The output should be 0.0.\nActual Result: The output is -0.0.\n\n**Environment Details Tested:**\n--Python Version: 3.12.5, Operating System: Windows 11.\n--Python Version: 3.12.3, Operating System: Ubuntu.\n\nAdditional Information: I have verified this issue on multiple machines and with different Python versions. The issue persists across all tested environments.\n\n### CPython versions tested on:\n\n3.12, 3.13\n\n### Operating systems tested on:\n\nLinux, Windows\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-123829\n* gh-123938\n* gh-123939\n* gh-124007\n* gh-124048\n* gh-124049\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/lykan89","@type":"Person","name":"lykan89"},"datePublished":"2024-09-07T17:07:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":19},"url":"https://github.com/123811/cpython/issues/123811"}
