I did not trust the notation of sign exponent mantisa and found another source about it. There was my orginal sequence of sign., mantisa, exponent. As far I remeber there is a sign for the mantisa and also a sign for the exponent. My source was fortran and intels PL/M at that time (1976) Best regards Ron_1st ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
