Function number_format without defined parameters dec_point and thousands_sep does not work properly for DBF number, because these parameters are taken from locales. Fof example thousand separator can ba a space, so it generate format such this: "1 000". And this value is not valid.

A correct call must be: number_format($value, $columnObj->getDecimalCount(), '.', '')
