Executed test cases
LibreOffice Calc 25.8.7.3 (tested 2026-08-06)
| Formula | Description | Result | Expected | Verdict |
|---|---|---|---|---|
| =MOD(7,3) | Both operands positive | 1 | 1 | Matched |
| =MOD(-7,3) | Excel/LO MOD result takes the SIGN OF THE DIVISOR, not truncated-remainder semantics | 2 | 2 C-style '%' would give -1; spreadsheet MOD gives 2 because result = n - d*FLOOR(n/d) |
Matched |
| =MOD(7,-3) | Negative divisor: result takes the sign of the divisor | -2 | -2 | Matched |
| =MOD(5,0) | Division by zero -> #DIV/0! | #DIV/0! | #DIV/0! | Matched |
