BigInteger Explicit Conversion (BigInteger to Int16)

Defines an explicit conversion of a BigInteger object to a 16-bit signed integer value.

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

public static explicit operator short (
	BigInteger value
)

Parameters

value
Type: System.Numerics.BigInteger
The value to convert to a 16-bit signed integer.

Return Value

Type: System.Int16
An object that contains the value of the value parameter.

ExceptionCondition
OverflowException

value is less than Int16.MinValue.

-or-

value is greater than Int16.MaxValue.

The overloads of the Explicit(Decimal to BigInteger) method define the types to which or from which a BigInteger 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 CShort in Visual Basic) is used. Otherwise, they display a compiler error.

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 Int16 data type. There is no loss of precision in the resulting Int16 value if the conversion is successful.

The following example illustrates the conversion of BigInteger values to Int16 values. It also handles an OverflowException that is thrown because the BigInteger value is outside the range of the Int16 data type.


// BigInteger to Int16 conversion.
BigInteger goodShort = 20000;
BigInteger badShort = 33000;

short shortFromBigInteger;

// Successful conversion using cast operator. 
shortFromBigInteger = (short) goodShort;
Console.WriteLine(shortFromBigInteger);

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