[Correct rational (double-float) formatting
Arjan Wekking <arjan@streamtech.nl>**20080725135212
 
 On Clozure CL (PPC32), (format "~f" (coerce 1/123 'double-float))
 returns "0.008130081300813009D0" which is not a number syntax
 PostgreSQL understands.
 
 In order to be sure that a format is used that is always supported,
 the formatting string was changed to generate the number in
 exponential notation which is accepted by PostgreSQL and which can be
 reliably generated by at least SBCL and Clozure CL (only CLs I've
 tested).
 
 The modified control string in this patch ("~,,,,,,'EE") will generate
 for the rational 1/123 "8.130081300813009E-3" which is accepted and
 interpreted properly by PostgreSQL.

Ryszard Szopa <ryszard.szopa@gmail.com>**20070905130310

 FIXNUM).
