BigInteger Implicit Conversion (UInt64 to BigInteger)

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

This API is not CLS-compliant. The CLS-compliant alternative is Double.

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

public static implicit operator BigInteger (
	ulong value
)

Parameters

value
Type: System.UInt64

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 a UInt64 value to a BigInteger value, as the following example shows.

ulong uLongValue = 1358754982;
BigInteger number = uLongValue;
number = number * 2 - uLongValue;
Console.WriteLine(number * uLongValue / uLongValue); // Displays 1358754982
