Remarks

SqlDecimal has different underlying data structures from its corresponding .NET Framework Decimal data type. Decimal has no concept of precision. It uses 3 DWORDs (12 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.
