BigInteger Explicit Conversion (BigInteger to Int32)

Defines an explicit conversion of a BigInteger object to a 32-bit signed integer value.

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

public static explicit operator int (
	BigInteger value


Type: System.Numerics.BigInteger
The value to convert to a 32-bit signed integer.

Return Value

Type: System.Int32
An object that contains the value of the value parameter.


value is less than Int32.MinValue.


value is greater than Int32.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 CInt 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 Int32 data type. There is no loss of precision in the resulting Int32 value if the conversion is successful.

The following example illustrates the conversion of BigInteger values to Int32 values. It also handles an OverflowException that is thrown because the BigInteger value is outside the range of the Int32 data type.
