📝 Walkthrough
Walkthrough
The error message in the inner_floordiv function was updated from "integer division by zero" to "integer division or modulo by zero" to more accurately reflect that the error applies to both division and modulo operations. No control flow or logic changes occurred.

Poem
🐰 A message so clear, now updated with care,
Division and modulo, both handled with flair,
No zero allowed in this mathematical dance,
The error now speaks of their shared circumstance!

| Title check |
⚠️ Warning |
The title 'Added doctest tests' is vague and does not reflect the actual change, which is modifying an error message in the integer floor division function. |
Update the title to accurately describe the main change, such as 'Update floor division error message to include modulo context' or 'Change integer division by zero error message'. |
| Docstring Coverage |
⚠️ Warning |
Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. |
You can run @coderabbitai generate docstrings to improve docstring coverage. |

130-136: Error message in inner_floordiv matches CPython behavior; however, inner_mod has an inconsistent error message.
The error message "integer division or modulo by zero" in inner_floordiv is correct—CPython uses this exact message for both floor division (//) and modulo (%) operations with integers. However, inner_mod (line 124) uses "integer modulo by zero", which differs from CPython's behavior and is inconsistent with inner_floordiv and inner_divmod.
Update inner_mod to use "integer division or modulo by zero" for consistency with CPython and the other integer division-related functions.
Note: The PR title mentions "Added doctest tests" but no doctest additions are visible in this diff.
