BigInteger Implicit Conversion (Int64 to BigInteger)

Defines an implicit conversion of a signed 64-bit integer to a BigInteger value.

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

public static implicit operator BigInteger (
	long value


Type: System.Int64

The value to convert to a BigInteger.

Return Value

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

The overloads of the Implicit method define the types from which a compiler can automatically convert a BigInteger value without an explicit casting operator (in C#) or a call to a conversion function (in Visual Basic). They are widening conversions that do not involve data loss and do not throw an OverflowException. This overload lets the compiler handle conversions from an Int64 value to a BigInteger value, as the following example shows.

long longValue = 1358754982;
BigInteger number = longValue;
number = number + (longValue / 2);
Console.WriteLine(number * longValue / longValue); // Displays 2038132473
