OracleDecimal Structure

The OracleDecimal structure represents an Oracle NUMBER in the database or any Oracle numeric value.

Class Inheritance

System.Object

  System.ValueType

    Oracle.DataAccess.Types.OracleDecimal

Declaration

// ADO.NET 2.0: C#
 public struct OracleDecimal : IComparable, INullable, IXmlSerializable

// ADO.NET 1.x: C#public struct OracleDecimal : IComparable, INullable

Thread Safety

All public static methods are thread-safe, although instance methods do not guarantee thread safety.

Remarks

OracleDecimal can store up to 38 precision, while the .NET Decimal data type can only hold up to 28 precision. When accessing the OracleDecimal.Value property from an OracleDecimal that has a value greater than 28 precision, an exception is thrown. To retrieve the actual value of OracleDecimal, use the OracleDecimal.ToString() method. Another approach is to obtain the OracleDecimal value as a byte array in an internal Oracle NUMBER format through the BinData property.

Example

// C#
 
using System;
using Oracle.DataAccess.Types;
 
class OracleDecimalSample
{
  static void Main(string[] args)
  {
    // Illustrates the range of OracleDecimal vs. .NET decimal
    OracleDecimal decimal1 = OracleDecimal.MinValue;
    OracleDecimal decimal2 = OracleDecimal.MaxValue;
    OracleDecimal decimal3 = new OracleDecimal(decimal.MinValue);
    OracleDecimal decimal4 = new OracleDecimal(decimal.MaxValue);
 
    // Print the ranges
    Console.WriteLine("OracleDecimal can range from\n{0}\nto\n{1}\n",
      decimal1, decimal2);
    Console.WriteLine(".NET decimal can range from\n{0}\nto\n{1}", 
      decimal3, decimal4);
  }
}

Requirements

Namespace: Oracle.DataAccess.Types
