to
Converts this BigInteger to an int. This conversion is analogous to a narrowing primitive conversion from long to int as defined in <cite>The Java Language Specification</cite>: if this BigInteger is too big to fit in an int, only the low-order 32 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigInteger value as well as return a result with the opposite sign.
Return
