  Constant Field Values
- twoToBitsMinus1
  
  public static BigInteger twoToBitsMinus1
  
  The period of the generator (2¹¹⁶ − 1).
- factor
  
  public static final BigInteger[] factor
  
  Factors of 2¹¹⁶ − - 1.
- cofactor
  
  public static final 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 Details
- mPow
  
  public static void mPow(BigInteger e)
  
  Computes the power to a given exponent, given the quadratures.
  
  Parameters:
  
  e - an exponent smaller than or equal to 2^BITS.
- main
  
  public static void main(String[] arg)
