Fix MATCH when comparing different numeric types (#1521)
Let MATCH compare numerics of different type (e.g. integers and floats).
```php
<?php
require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
// Row: 1, 2, 3, 4, 5. MATCH for 4.6.
$sheet->getCell('A1')->setValue(1);
$sheet->getCell('A2')->setValue(2);
$sheet->getCell('A3')->setValue(3);
$sheet->getCell('A4')->setValue(4);
$sheet->getCell('A5')->setValue(5);
$sheet->getCell('B1')->setValue('=MATCH(4.6, A1:A5, 1)');
// Should echo 4, but echos '#N/A'.
echo $sheet->getCell('B1')->getCalculatedValue() . PHP_EOL;
// Row: 1, 2, 3, 3.8, 5. MATCH for 4.
$sheet->getCell('C1')->setValue(1);
$sheet->getCell('C2')->setValue(2);
$sheet->getCell('C3')->setValue(3);
$sheet->getCell('C4')->setValue(3.8);
$sheet->getCell('C5')->setValue(5);
$sheet->getCell('D1')->setValue('=MATCH(4, C1:C5, 1)');
// Should echo 4, but echos 3.
echo $sheet->getCell('D1')->getCalculatedValue() . PHP_EOL;
```
