SqlDecimal has different underlying data structures from its corresponding .NET Framework Decimal data type. Decimal has no concept of precision. It uses 3 bytes to store the actual data, and therefore has a maximum scale of 28. The data range is -79,228,162,514,264,337,593,543,950,335 through 79,228,162,514,264,337,593,543,950,335. SqlDecimal has both precision and scale. It uses 4 unsigned 4-byte integers to store the actual data, and therefore has maximum precision and scale of 38. The data range is - 10^38 +1 through 10^38 - 1.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
