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.
