      • bits

        public static int bits
        The number of bits of state of the generator.
      • twoToBitsMinus1

        public static java.math.BigInteger twoToBitsMinus1
        The period of the generator (2bits − 1).
      • factor

        public static final java.math.BigInteger[] factor
        Factors of the Fermat “primes” up to the eleventh (22048 + 1).
      • cofactor

        public static final java.math.BigInteger[] cofactor
        An array of cofactors. Entry 0 ≤ i < numCofactors contains twoToBitsMinus1 divided by factor[i]. Note that some entries can be null if bits is less then 4096.
      • numCofactors

        public static int numCofactors
        The actual number of valid entries in cofactor.
    • Method Detail

      • mPow

        public static void mPow​(java.math.BigInteger e)
        Computes the power to a given exponent, given the quadratures.
        Parameters:
        e - an exponent smaller than or equal to 2bits.
      • main

        public static void main​(java.lang.String[] arg)
