Description Dave Peterson 2010-02-15 15:48:53 UTC 
In the definition of the function "scientificMap", it appears that the value of the exponent part is subtracted from the significand part, rather than the two being properly multiplied together.

This error was introduced in datatypes revision 1.7.2.8, 17 Jun 2004, and apparently never before noticed.  :-(  (Just prior to that revision, the operation was shown as a multiplication, at the time denoted by an asterisk rather than a "real" multiplication sign.)

The obvious fix is to replace the minus sign with a multiplication sign in two places.
