The method defines the decrement operation for BigInteger values. It enables code such as the following:
Languages that do not support custom operators can call the Subtract method instead. For example:
Because BigInteger objects are immutable, the operator creates a new BigInteger object whose value is one less than the BigInteger object represented by value. This means that repeated calls to may be expensive.
