BigInteger Explicit Conversion (BigInteger to Decimal)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Defines an explicit conversion of a BigInteger object to a Decimal value.

Namespace:   System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)

public static explicit operator decimal (
	BigInteger value


Type: System.Numerics.BigInteger

The value to convert to a Decimal.

Return Value

Type: System.Decimal

An object that contains the value of the value parameter.

Exception Condition

value is less than Decimal.MinValue.


value is greater than Decimal.MaxValue.

The overloads of the Explicit(Decimal to BigInteger) method define the types to which or from which a BigInteger object can be converted. Language compilers do not perform this conversion automatically because it can involve data loss. Instead, they perform the conversion only if a casting operator (in C#) or a conversion function (such as CType or CDec in Visual Basic) is used.

Because this operation defines a narrowing conversion, it can throw an OverflowException at run time if the BigInteger value is outside the range of the Decimal data type.

The following example illustrates the conversion of BigInteger to Decimal values. It also handles an OverflowException that is thrown because the BigInteger value is outside the range of the Decimal data type.

// BigInteger to Decimal conversion.
BigInteger goodDecimal = 761652543;
BigInteger badDecimal = (BigInteger) Decimal.MaxValue; 
badDecimal += BigInteger.One;

Decimal decimalFromBigInteger;

// Successful conversion using cast operator.
decimalFromBigInteger = (decimal) goodDecimal;

// Handle conversion that should result in overflow.
   decimalFromBigInteger = (decimal) badDecimal;
catch (OverflowException e)
   Console.WriteLine("Unable to convert {0}:\n   {1}", 
                     badDecimal, e.Message);
