In August, Dalton Chiscolm sued Bank of America, the largest US bank and its board, demanding that "$US1,784 billion, trillion" be deposited into his account the next day.He also demanded an additional $US200,164,000, court papers show.Attempts to reach Mr Chiscolm were unsuccessful and a Bank of America spokesman declined to comment."Incomprehensible," US District Judge Denny Chin said in a brief order released in Manhattan federal court."He seems to be complaining that he placed a series of calls to the bank in New York and received inconsistent information from a 'Spanish woman,'" the judge wrote."He apparently alleges that cheques have been rejected because of incomplete routing numbers."It is larger than a sextillion dollars, or a 1 followed by 21 zeros.Mr Chiscolm's request is equivalent 1 followed by 22 digits.
