[Bug 61495] New: FormulaEvaluator does evaluate Number wrong. [=TEXT(nr;FORMAT)]

Bugzilla from bugzilla@apache.org

            Bug ID: 61495
           Summary: FormulaEvaluator does evaluate Number wrong.
                    [=TEXT(nr;FORMAT)]
           Product: POI
           Version: 3.16-FINAL
          Hardware: PC
            Status: NEW
          Severity: regression
          Priority: P2
         Component: SS Common

Created attachment 35300

Text Excel File

I am reading an excel file with lots of huge formulas.
The Problem occurs, with the folowing Formula:

Orginal: =WENN(TEST!A2="";"";VERKETTEN("D";" ";TEXT(TEST!A2;"00,00")))
Translated: =IF(TEST!A2="";"";CONCAT("D";" ";TEXT(TEST!A2;"00,00")))

The issue is that the excel file in my Office Excel does show up in a correct
manner since it's localization is GERMAN. However reading it in with, Apache
POI and using the FormulaEvaluator does mess up the results. However using the
format "0.00" does indeed result in a correct manner, so I do assume it's an
localization issue. I also used a org.apache.poi.ss.usermodel.DataFormatter
with the hope to tell it my Locale. However both methods do fail. I did
recreate a minimal test.xlsm and i tested this issue with the following apache
poi releases: LATEST 3.17 Beta - "poi-bin-3.17-beta1-20170701", LATEST 3.16 -
"poi-bin-3.16-20170419", 3.15 Beta2 - "poi-3.15-beta2".

I did create also a Test Class:

####TEST CLASS START####


import java.io.FileInputStream;
import java.util.Locale;
import java.util.stream.IntStream;

import org.apache.poi.ss.usermodel.DataFormatter;
import org.apache.poi.ss.usermodel.FormulaEvaluator;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;

public class POITester_3_17 {

        private static final String WORKBOOK_PATH =
"C:\\Users\\l.dag\\Desktop\\test.xlsm";
        private static final String SHEET_NAME = "TEST";

        public static void main(String[] args) throws Exception {
                //Read in Workbook as usual
                final FileInputStream fis;
                final Workbook wb = WorkbookFactory.create(fis = new
FileInputStream(POITester_3_17.WORKBOOK_PATH));
                fis.close();
                //Read end ...

                //Load Sheet + FormulaEvaluator
                final Sheet sheet = wb.getSheet(POITester_3_17.SHEET_NAME);


                final FormulaEvaluator fe =
wb.getCreationHelper().createFormulaEvaluator();
                final DataFormatter df = new
DataFormatter(Locale.getDefault());
                //Load end

                //Evaluate and Print out the cells to test [Hardcoded location,
for test case]
                IntStream.range(0,2).mapToObj(sheet::getRow).map(r ->
r.getCell(1)).forEach(c -> {                      
                        System.out.println(fe.evaluate(c));
                        System.out.println(df.formatCellValue(c, fe));
                });
        }

}

####TEST CLASS END####

Resulting Output using test.xlsm:

####OUTPUT START####
org.apache.poi.ss.usermodel.CellValue ["D 67,10"]
D 67,10
org.apache.poi.ss.usermodel.CellValue ["D 00.68"]
D 00.68
####OUTPUT END####

####WHAT MY EXCEL SHOWS START####
67,10   D 0.067
68,20   D 68,20
####WHAT MY EXCEL SHOWS END####
