In engineering-notation the exponent is always an integer multiple of 3. SCM scales the matissa to be between 1 and 1000, and omits the exponent when it is 0. Engineering-notation is good for viewing floating-point numerical data. Unless the data is very erratic, one can tell from looking at the mantissas when the exponents have changed. _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
