UPOS1151 — FiscalPrinter: Unclear string format for totalizer values returned by getData

The format of string data returned by the getData is unclear for totalizer values. It should be clarified.
Since totalizer values (e.g. grand total) may exceed limits of receipt total values, it is not clear that such values may fit into values described as type currency in the UPOS specification. In addition, there is no specification which kind of data type shall be used for totalizers.
Expecting that OPOS uses CURRENCY, POS for .NET decimal and Java implementations perhaps BigDecimal for totalizers, getData should return totalizer values with decimal point as returned by the in-built string conversions. For example, a totalizer of 12345.67 should be returned as "12345.67".
