BigInteger.UnaryNegation Operator

Negates a specified BigInteger value.

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

public static BigInteger operator -(
	BigInteger value
)

Parameters

value
Type: System.Numerics.BigInteger
The value to negate.

Return Value

Type: System.Numerics.BigInteger
The result of the value parameter multiplied by negative one (-1).

The UnaryNegation method defines the operation of the unary negation operator (or the additive inverse operator) for BigInteger values. The operation produces a value that results in 0 (zero) when it is added to the original number. Languages that do not support custom operators can call the Negate method instead.

The following example illustrates three different ways to negate the value of a BigInteger object.


BigInteger number = 12645002;

Console.WriteLine(BigInteger.Negate(number));        // Displays -12645002
Console.WriteLine(-number);                          // Displays -12645002
Console.WriteLine(number * BigInteger.MinusOne);     // Displays -12645002
