Decimal precision - C#

Question

All,

For a decimal value of 1 billion being retrieved from SQL Server where the associated datatype is Numeric (28,10), I am running into Conversion overflow exception. From MSDN:

The .NET Framework decimal data type allows a maximum of 28 significant digits

I need to clarify if the digits here refer to the binary form or decimal form itself?

Answer 1

In SQL Server for Numeric and Decimal datatypes, this defines a maximum of 28 decimal digits in total (the precision) with a maximum of 10 decimal places to the right of the decimal point (the scale), thus giving a maximum of 18 dp to the left of the point.

Answer 2

The limitation is imposed by the decimal representation and the 28 significant digits refer to 28 decimal digits.
