Commit IDs + +- Starting commit: `0289c7f917` (end of Milestone A) +- IFNA (initial): `082ee9a94b` (source + tests) +- SKEWP (initial): `6a3f45420f` (source + tests) +- IFNA + SKEWP corrections (B.1): `c9db33542f` (source + tests + report) +- Branch: `openformula` + +## 2. Source-Mining Findings + +### IFNA + +**Before this milestone, IFNA did not exist in AOO.** The only reference was an +Excel-filter stub at `main/sc/source/filter/excel/xlformula.cxx:404`: +`EXC_FUNCENTRY_ODF( ocNoName, 2, 2, 0, "IFNA" )` — an `ocNoName` placeholder +with no opcode, no interpreter method, no `scfuncs.src` entry, and no +`core_resource.src` entry. + +**IF (ocIf=6)** provides the lazy-evaluation pattern to reuse. IF uses +jump-based compilation (`FormulaCompiler.cxx:1073-1128`) where the compiler +generates jump addresses for the value, fallback, and end paths. At runtime, +`ScInterpreter::ScIfJump()` (`interpr1.cxx:93`) pops the condition and jumps +to the appropriate path, evaluating only the taken branch. It calls +`MatrixDoubleRefToMatrix()` first to convert references to matrices, then +switches on `GetStackType()`. + +**IFNA needs the same lazy-evaluation machinery** because `value_if_na` must +not be evaluated when `value` is not #N/A. Simply evaluating both arguments +eagerly would be wrong: e.g. `IFNA(5; 1/0)` must return 5, not #DIV/0!. + +**Error code:** #N/A = `NOTAVAILABLE` (0x7fff), defined in +`main/formula/inc/formula/errorcodes.hxx:81`. The interpreter tracks errors +via `nGlobalError` and `FormulaToken::GetError()` / `GetType() == svError`. + +### SKEWP + +**Before this milestone, SKEWP did not exist in AOO.** The only reference was +an Excel-filter stub at `main/sc/source/filter/excel/xlformula.cxx:415`: +`EXC_FUNCENTRY_ODF( ocNoName, 1, MX, 0, "SKEWP" )`. + +**SKEW (ocSchiefe=325)** exists at `interpr3.cxx:3081` (`ScInterpreter::ScSkew`), +using the helper `CalculateSkew()` (`interpr3.cxx:2969`) for data collection. +`CalculateSkew` collects numeric values from doubles, single/double references, +ref lists (via `ScValueIterator`), and matrices — skipping empty cells, text, +and logical values, propagating errors via `nGlobalError`. + +**ScSkew formula** (sample skewness): +``` +mean = sum / N +stdDev = sqrt( sum((xi-mean)^2) / (N-1) ) // sample, N-1 +result = (xcube * N) / ((N-1) * (N-2)) // sample skewness +``` + +**SKEWP formula** (population skewness, ODF 1.4 §6.18.63): +``` +mean = sum / N +sigma = sqrt( sum((xi-mean)^2) / N ) // population, N +result = (1/N) * sum( ((xi-mean)/sigma)^3 ) +``` + +## 3. Defects Found and Corrected (B.1) + +### IFNA: reference handling was broken + +The initial `ScIfna()` implementation only peeked at `pStack[sp-1]` assuming +it was an `svError` token. This works for direct `NA()` calls but fails for: + +- **Cell references** (`svSingleRef`): a reference token on the stack is not + an error token — it must be dereferenced to check the cell's error code. +- **Range references** (`svDoubleRef`): same issue, needs implicit intersection. +- **Reference lists** (`svRefList`) and **matrices** (`svMatrix`): not handled. + +The initial code also had a stack-safety issue: `--sp` discards the token +without calling `PopError()`, which is fine for `svError` but would be wrong +for other types. + +### SKEWP: argument semantics inconsistent + +`CalculateSkew()` (shared with SKEW) treated direct scalar text (`svString`) +as `errIllegalParameter` via the `default` case, but skipped text in ranges +and matrices. This made `SKEWP(1;"text";2)` fail with an error instead of +returning 0 (skipping text, evaluating `{1, 2}`). + +### SKEWP: error propagation lost original error code + +When a direct error argument (e.g. `1/0`) was passed, `svError` fell into +`CalculateSkew()`'s `default` → `SetError(errIllegalParameter)`, replacing +the original error (e.g. `#DIV/0!`) with a generic "illegal parameter" error. + +## 4.

IFNA Semantics and Error-Handling Decisions + +### Lazy evaluation via jump-based compilation + +`FormulaCompiler.cxx` generates code for `IFNA(value; value_if_na)` as: + +``` +[value code] [IFNA token(jump[0]=2)] [fallback code] + jump[1] jump[2] +``` + +- `jump[1]` = address where fallback code begins +- `jump[2]` = address after fallback (end) + +At runtime, `ScInterpreter::ScIfna()` (`interpr1.cxx:324`): + +1. Switches on `GetStackType()`: + - **`svError`**: Peeks at error code. If `NOTAVAILABLE` (#N/A), discards + the token (`--sp`) and jumps to `jump[1]` (fallback). Otherwise leaves + the error on the stack and jumps to `jump[2]` (end, propagate error). + - **`svSingleRef` / `svDoubleRef`**: Pops the reference via + `PopDoubleRefOrSingleRef()` (which performs implicit intersection for + ranges), gets the cell via `GetCell()`, checks `GetCellErrCode()`: + - `#N/A` → jump to fallback (reference already popped, nothing on stack) + - Other error → `PushError(nErr)`, jump to end + - Value → `PushCellResultToken(true, aAdr, NULL, NULL)`, jump to end + - **`svRefList` / `svMatrix`**: Jumps to end, returning the value as-is. + IFNA is not an array-forcing function; per-element #N/A substitution is + not implemented. This is a documented limitation. + - **Default** (double, string, etc.): Jumps to end, keeping the value. + +2. `value_if_na` is never compiled/evaluated unless `value` is #N/A — the + compiler only emits fallback code after the jump target, so it is simply + never reached when value is not #N/A. + +3. `value` is evaluated exactly once. + +4. Errors other than #N/A are propagated unchanged — `ScIfna` does not clear + `nGlobalError` for non-#N/A errors. + +### Supported input forms + +| Input form | Handling | +|------------|----------| +| `NA()` (direct #N/A error) | Recognized as `svError` with `NOTAVAILABLE` → fallback | +| Cell reference containing #N/A | Dereferenced via `PopSingleRef`, cell error checked → fallback | +| Cell reference containing other error | Dereferenced, error pushed → propagated | +| Cell reference containing value | Dereferenced, cell value pushed → returned | +| Range reference | Implicit intersection via `DoubleRefToPosSingleRef`, first cell checked | +| Reference list | Returned as-is (documented limitation) | +| Matrix | Returned as-is (documented limitation) | +| Direct text/number/logical | Returned unchanged | + +### Documented limitation: matrix handling + +IFNA is not an array-forcing function in OpenFormula 1.4. When `value` is a +matrix, the current implementation returns the matrix as-is without +per-element #N/A substitution. Implementing full element-wise IFNA would +require a `ScJumpMatrix`-based approach (as used by `ScIfJump`) to evaluate +the fallback per element, which is beyond the scope of this milestone. + +## 6. SKEWP Formula and Edge-Case Decisions + +### Population standard deviation (sigma, denominator N): + +``` +sigma = sqrt( sum((xi - mean)^2) / N ) +``` + +This differs from SKEW's sample standard deviation (denominator N−1). + +### Population skewness result: + +``` +result = (1/N) * sum( ((xi - mean) / sigma)^3 ) +``` + +### Edge cases: + +| Case | Behavior | Rationale | +|------|----------|-----------| +| N = 0 (no args) | Error | `CalculateSkew` requires ≥1 param | +| N = 1 | Error | `sigma = 0`, zero variance | +| Constant data (zero variance) | Error | `sigma = 0`, division by zero | +| Two observations, non-constant | Valid result | e.g. SKEWP(1;2) = 0 | +| Error in input | Propagated | Original error code preserved | +| Text in direct argument | Skipped | Consistent with range/matrix handling | +| Empty cells | Skipped | `CalculateSkew` skips non-numeric | +| Matrix / array input | Supported | `CalculateSkew` handles `svMatrix` | + +### Numerical stability + +Uses the same two-pass approach as SKEW (compute mean first, then squared +deviations). No unnecessary integer conversions. The `fSigma == 0.0` check +avoids division by zero for zero-variance data. + +### SKEW vs SKEWP difference + +For `{1, 1, 2}`: +- SKEWP = 1/√2 ≈ 0.7071067812 (population) +- SKEW = √3 ≈ 1.7320508076 (sample) +They differ, confirming the formulas are distinct. + +## 7. Function Registration and Documentation + +**Opcode allocation:** IFNA=409, SKEWP=410. `SC_OPCODE_LAST_OPCODE_ID` +updated from 408 to 410. `SC_OPCODE_STOP_2_PAR` moved from 409 to 411 so both +new functions fall in the 2-parameter range (`START_2_PAR=201` to +`STOP_2_PAR=411`), which is already handled by the compiler's symbol-table +construction (`FormulaCompiler.cxx:452-462`) and 2-param compilation branch +(`FormulaCompiler.cxx:1014`). + +**Compiler:** IFNA uses a dedicated jump-based compilation block (modeled on +ocIf/ocChose at `FormulaCompiler.cxx:1073-1128`). SKEWP uses the existing +2-parameter function compilation path. + +**Interpreter:** `ScIfna` in `interpr1.cxx:324`, `ScSkewP` in +`interpr3.cxx:3081`. Dispatch in `interpr4.cxx`. + +**Resources:** `core_resource.src` entries in all 3 Resource blocks +(ENGLISH_ODFF, ENGLISH, localized). `scfuncs.src` entries with function group +(LOGICAL for IFNA, STATISTIC for SKEWP), parameter names/descriptions, and +HID references. + +**Excel import/export:** `xlformula.cxx` stubs updated from `ocNoName` to +`ocIfna`/`ocSkewP`, so Excel files containing IFNA/SKEWP are mapped to the +real implementations. + +**ODF save/reload:** Function names are written as standard `IFNA`/`SKEWP` +per `core_resource.src` ODFF mappings, so they survive ODF save/reload. + +**Help documentation:** `scfuncs.src` entries include English descriptions +and parameter documentation. No separate helpcontent2 files were added (the +existing convention for recently added functions like EASTERSUNDAY also uses +only `scfuncs.src`). + +## 8.

The `main/solver/510/` directory +contains only a partial `xml2cmp` build; the `sc` module is not built. No +`Module_*.mk` makefiles exist in the source tree (they are generated by AOO's +gbuild configure step, which has not been run). + +**Attempted:** `dmake -C main/sc/source/core/tool interpr1.obj` → prints dmake +usage only (no makefile present). + +**Result:** Build and test execution were **not possible** in this environment. +The calcval ODF 1.4 tests require a built office and (per `test/odf-validate/` +README) run on macOS. + +**Static verification performed:** +- Brace balance: 0 for all modified C++ files (`interpr1.cxx`, `interpr3.cxx`) +- Opcode values: IFNA=409, SKEWP=410, LAST_OPCODE_ID=410, STOP_2_PAR=411 — + all unique and consistent +- All identifiers used (`formula::svError`, `NOTAVAILABLE`, `pStack`, `sp`, + `aCode`, `pCur`, `PopDoubleRefOrSingleRef`, `PushCellResultToken`, + `GetCellErrCode`, `GetCell`, `PopError`, `PopString`) were already present + in the respective function scopes + +**For validation in a configured build environment:** +1.

Not Verified and Why + +- **Real build and runtime tests:** No configured AOO build tree exists in + this environment.

Error + tests therefore use `#ERR`, which cannot distinguish the original error + from a substituted one. + +## 11. Remaining Compatibility and Conformance Concerns + +- **IFNA matrix evaluation:** IFNA is not an array-forcing function. When + `value` is a matrix or reference list, the current implementation returns + the value as-is without per-element #N/A substitution. Per OpenFormula 1.4 + §6.15.13, IFNA's behavior with array inputs is implementation-defined. + Full element-wise support would require `ScJumpMatrix`-based infrastructure + (as used by `ScIfJump`). +- **IFNA range references:** Uses implicit intersection + (`DoubleRefToPosSingleRef`) to check the first cell of a range. If the + range contains #N/A in a non-intersected cell, it is not detected. +- **SKEWP text handling change:** `CalculateSkew()` now skips direct scalar + text (`svString`) instead of raising `errIllegalParameter`. This changes + SKEW behavior identically (both functions share `CalculateSkew()`). The + change makes direct-argument text handling consistent with range/matrix + handling, which is more consistent with OpenFormula's NumberSequence + definition (text excluded). Both SKEW and SKEWP are affected equally. +- **SKEWP error propagation:** Direct error arguments now preserve the + original error code instead of replacing it with `errIllegalParameter`. + This changes SKEW behavior identically (both functions share + `CalculateSkew()`). Both functions now propagate the original error. + +## 12.

Empty cell handling + +**[CONFIRMED]** `HasCellEmptyData()` (interpre.hxx:240) "Really empty or inherited emptiness". `HasCellValueData()` (interpre.hxx:243). `HasCellStringData()` (interpre.hxx:244). `PushCellResultToken` with `bDisplayEmptyAsString` (interpre.hxx:308). Empty cells normally treated as 0 in numeric contexts (GetCellValueOrZero interpre.hxx:231). + +**[ODF 1.4 migration]** COUNTA/COUNTBLANK empty-cell semantics changed in ODF 1.4 vs 1.3. AOO's `ScCount2` (COUNTA) and `ScCountEmptyCells` (COUNTBLANK) need re-check against ODF 1.4. **[UNVERIFIED]** COUNTBLANK of "" impl-defined (odf_docs item 6.13.8). + +## 7.
