Method Detail

value

public static BigInteger value(BigInteger i)
This method is used in the RAC implementation of prefix ++ and -- over \bigint's. Given \bigint bi, we translate ++bi into value(bi = bi.add(BigInteger.ONE)). The reason that ++bi is not simply transated into (bi = bi.add(BigInteger.ONE)) is that expressions cannot be used where a statement is expected where as a method call like value(...) can.


first

public static BigInteger first(BigInteger i,
                               BigInteger j)
This method is used in the RAC implementation of postfix ++ and -- over \bigint's. E.g. given \bigint bi, we translate bi++ into first(bi, bi = bi.add(BigInteger.ONE)).
