>    Affects Versions: 8.x

> Problem 1:  The parser defaults to parsing literals that look like bigdecimal as doubles, which have no scale.  
> Workaround (which is on devcentral): You can avoid the above conversions by wrapping the values in a convert in the query (example:  "convert('123.00', BigDecimal )").
> A better fix is update the parser to look for loss of scale information and to use the bigdecimal type instead.
> Problem 2: default division behavior JBEDSP-305
> Problem 3: No explicit control via the parser
> It would be good to provide explicit precision and scale via "convert(xxx, BigDecimal(10, 2))" - side note bigdecimal is a bad name for this type.  it should really just be decimal
> Reference:  This is related to Issue Tracker Issue 175485.
