* Raise underflow when close to 0 decfloat value casted to double * High precision NUMERIC datatype based on DECFLOAT * Fixed bulk insert mode in isql for decfloat values * Enforce correct decQuad format after arithmetic operations * Minimum docs for high precision NUMERIC/DECIMAL * Some fixes of code suggested by Adriano: - Use "const" keyword for Decimal128 constants declared internally - Remove unneeded buffer initialization - Remove unused function makeDecimalFixed() - Follow firebird naming conventions to make code better readable and avoid possible conflicts with various .h files - Added forgotten scale for DecimalFixed
