[1225]Can I get a BigInteger.pow(BigInteger)?
By Dan nqly { at } hotmail { dot } com on 2004/12/23 19:30:42  Rate
Dear Sir/Madam: 
  
  
 Could you please let me know how I get a BigInteger.pow ( BigInteger ) like in BigInteger.modPow ( BigInteger, BigInteger ) instead of BigInteger.pow ( int )  because by narrowing the bigInteger to an integer only lower 32 bits can be obtained, which loses a lot of information. 
  
  
 Thank you ever so much for your gracefull assistance.  
 Wish you merry Christmas and happy New Year! 
  
  
 Sincerely Yours, 
 Dan

More accurate: 
  
  
 BigInteger c = new BigInteger ( "300" ) ;
