Decimal Digit Limitation on Functions
In TDV version 7.0.2 or later, add, subtract, multiply, divide, and modulo operators in functions follow SQL Server's behavior, which prevents precision/scale from exceeding 38 digits. But customers might need to wrap CASTs around columns in cached tables whose data types no longer match in such situations, so a configuration parameter has been made available to restore pre-7.0.2 behavior.
The name of the boolean configuration parameter is Decimal digit limitation in functions:
• When set to True (the default), add, subtract, multiply, divide, and modulo operators in functions prevent precision/scale from exceeding 38 digits.
• When set to False, add, subtract, multiply, divide, and modulo operators in functions allow precision/scale to exceeding 38 digits.
