BigInteger.Negate Method

Negates a specified BigInteger value.

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

public static BigInteger Negate(
	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).

Negation obtains the additive inverse of a number. The additive inverse of a number is a number that produces a value of zero when it is added to the original number.

The Negate method is implemented for languages that do not support custom operators. Its behavior is identical to negation using the unary negation operator. In addition, the Multiply method is a useful substitute for the negation operator when instantiating a BigInteger variable, as shown in the following example.


// The statement
//    BigInteger number = -Int64.MinValue;
// produces compiler error CS0220: The operation overflows at compile time in checked mode.
// The alternative:
BigInteger number = BigInteger.Negate(Int64.MinValue);


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