Igor Sapego commented on IGNITE-2879:
-------------------------------------
In the end, I decided to implement my own solution which is not based on Java
classes but is compatible with them. It conststs of two classes -
{{BigInteger}} and {{Decimal}}. {{BigInteger}} class implements most of the
functionality, including multiplication, division, pow and so on, while the
{{Decimal}} class implemented as an {{BigInteger}} with a scale and only deals
with operations that could affect the scale of the decimal number. Only minimal
set of methods have been implemented which is needed to be able to deal with
adjustment of the scale of the Decimals as required by the ODBC. This set
contains of {{SetScale()}}, {{GetScale()}}, {{GetPrecision()}} and input/output
operators for the {{Decimal}} class. All other methods have been implemented in
order to achieve this functionality.
> ODBC: Add support for Decimal type (SQL_NUMERIC_STRUCT).
