ODD in Calligra Sheets: Round to an odd integer

If a display must have an odd number of columns to leave one clearly centred column, you can plan for the next odd count. ODD is a rounding operation, not a test of whether the current value is odd. The separate ISODD function returns a logical value instead [1].

=ODD(value)

value (required) is a numeric literal, numeric calculation or reference to a cell containing a numeric value. The official KDE documentation identifies the argument as a floating-point value and the return type as numeric [1]. The shipped 26.08.2 math registry defines the ODD function name [2]. There is one argument, with no optional rounding-precision or default argument described.

KDE explicitly describes rounding upward for positive inputs and downward for negative inputs. It states ODD(0) = 1 and gives negative input −2 → −3. It also shows ODD(1.2) → 3 and ODD(2) → 3 [1]. These are documented expected results, not observed outputs from our own running copy.

Locale and formula entry: Begin each formula with =. The one-argument ODD expression needs no internal argument separator; the official English KDE handbook writes multiple-argument formulas with semicolons. Use the app’s Insert → Function dialog and numeric locale settings when working with decimal commas or importing another spreadsheet [3].

Create a new sheet with the following input values. Use C for the formula and D for your own notes, if useful.

Step 1: Label A1 Layout, B1 Requested columns, and C1 Rounded odd columns. Enter numeric values in column B exactly as shown; use -2 as a number for the deliberately negative test.

Step 2: Enter =ODD(B2) in C2. Expected 1, not 0 — KDE specifies this exceptional baseline explicitly [1].

Step 3: Copy or re-enter the function with B3–B6 as arguments. KDE independently confirms the first four expected results; C6’s 7 is independently derived from the documented rounding definition (6 is even, so the next larger odd integer is 7). None of these formulas has been executed in Calligra in this batch.

Step 4: Keep the negative test row only as a semantics check; a real layout should generally reject negative column counts rather than applying ODD to them.

For the real six-column requirement on row 6, enter this in D6:

=ODD(B6)-B6

Expected D6: 1, because ODD(6) is expected to be 7, and 7 − 6 = 1. You can use this difference to document the extra column added for a centred layout. This is a simple planning difference, not a claim that the physical display was built.

To provide a readable message instead, try in E6:

=IF(ODD(B6)=B6;"Already odd";"Add a column")

• ODD does not mean ISODD: ODD returns a number (e.g., 3); ISODD returns true/false. KDE lists both functions separately [1].
• Zero is special: =ODD(0) is documented to return 1; it does not preserve zero. Do not use ODD as an identity function when zero is a meaningful sentinel value.
• Negative inputs: KDE explicitly documents =ODD(-2) → −3 and says negative values round downward, so do not assume mathematical ceiling to −1. The meaning of a negative capacity remains a data-quality problem.
• Decimal text versus numeric values: A cell that visually contains 1.2 could be text after CSV import, or could use the wrong decimal separator. KDE’s ODD page does not specify every text-conversion or error outcome; inspect types before assuming a result.
• Precision/large values: The cited handbook does not guarantee every boundary behaviour of very large floating-point numbers. Do not use this article to certify numerical limits or platform-specific rounding.
• Function spelling: =ODD(B6;2) adds an unsupported second argument. Use =ODD(B6).

1. Use the control =ODD(2) and compare it to KDE’s published expected 3 [1].
2. Confirm the input cell is numeric and the reference is in the intended row.
3. If the result is 1 for zero input, this is specified behaviour, not a spreadsheet fault.
4. If a formula gives a parsing error, check the leading equals sign, parentheses and locale; KDE explains that #VALUE! may indicate an expression it cannot understand [3].
5. If the visible result is replaced by a narrow-cell warning, widen the cell before changing the formula [3].
6. Recheck any workbook moved from Excel or LibreOffice using representative zero, negative, decimal and whole-number cases.

Microsoft Excel’s ODD(number) is documented with similar away-from-zero rounding and explicitly describes −2 → −3 [4]. LibreOffice Calc and Google Sheets provide odd-integer rounding, but their localized formula separators, numerical coercion and workbook conversions should be tested rather than assumed. The Excel error rules in Microsoft’s reference are not proof of identical Calligra error reporting. Do not confuse Excel’s ISODD Boolean test with ODD numerical rounding.
