This is:

- [1 ] a bug report
- [ ] a feature request
- [ ] **not** a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

Keep a decimal number stay original from a PHP array,

As you can see at the image below:
Real value: 149819.78,
Formatted value: 149819.7800

What is the current behavior?

Format is OK, but not the actual value.

What are the steps to reproduce?

Please consider that you have an array like this:

$array = [
    0 => [
        'bruto' => '149819.7800'
        'volume' => '153.0000'
    ]
    1 => [
        'bruto' => '10594.0000'
        'volume' => '15.5650'
    ]
    2 => [
        'bruto' => '15750.0000'
        'volume' => '25.0000'
    ]
    3 => [
        'bruto' => '17263.0800'
        'volume' => '63.4618'
    ]
    4 => [
        'bruto' => '66600.0000'
        'volume' => '75.0000'
    ]
    5 => [
        'bruto' => '16128.0000'
        'volume' => '30.0000'
    ]
    6 => [
        'bruto' => '14280.0000'
        'volume' => '30.0000'
    ]
    7 => [
        'bruto' => '4806.4000'
        'volume' => '91.1700'
    ]
    8 => [
        'bruto' => '20732.0000'
        'volume' => '25.0000'
    ]
    9 => [
        'bruto' => '13004.2300'
        'volume' => '44.6290'
    ]
    10 => [
        'bruto' => '13929.0000'
        'volume' => '21.0080'
    ]
    11 => [
        'bruto' => '13280.0000'
        'volume' => '25.0000'
    ]
    12 => [
        'bruto' => '11929.0000'
        'volume' => '15.3400'
    ]
    13 => [
        'bruto' => '2884.9000'
        'volume' => '16.6950'
    ]
]

Please provide a [Minimal, Complete, and Verifiable example](https://stackoverflow.com/help/mcve) of code that exhibits the issue without relying on an external Excel file or a web server:

```php
<?php

        $spreadsheet = IOFactory::createReader('Xls')->load(
            Yii::$app->basePath . '/modules/utilities/views/flat-file-import/ssm/_header_bea_cukai_format.xls'
        );
        $activeSheet = $spreadsheet->setActiveSheetIndexByName('Detil');
        $activeSheet->fromArray($this->getTabDetil(), '', 'A2'); // $this->getTabDetil() is an array as a mention before
        $highestRow = $activeSheet->getHighestRow();
        for ($i = 2; $i <= $highestRow; $i++) {
            $activeSheet->getStyle('A' . $i)->getNumberFormat()->setFormatCode('0.0000');
            $activeSheet->getStyle('B' . $i)->getNumberFormat()->setFormatCode('0.0000');
        }

       # Sending headers to force the user to download the file
        $objWriter = IOFactory::createWriter($spreadsheet, 'Xls');

        header('Content-Type: application/vnd.ms-excel');
        header('Content-Disposition: attachment;filename="' . time() . $this->flatFileImport->id . '.xls"');
        header('Cache-Control: max-age=0');
        $objWriter->save('php://output');
        exit;

A number on the formula bar will display as Excel wishes to display it; this will be without trailing zeros in the decimal portion. You can see the same behavior in Excel quite easily - if you enter 1.00 in a cell (with default formatting), Excel will display it as 1 in both the cell and the formula bar. What kind of problem is this causing for you? In particular, why do you feel that the value it is displaying is "wrong"?

If, as it seems, you want the cell contents to be treated as a string, you might want to try StringValueBinder.
