Overview
Comment:Changes to completely remove all floating point ops if SQLITE_OMIT_FLOATING_POINT defined. Note that w/o fp, date/time, round, nan, etc. are all gone or limited in functionality. Updated some of the test scripts to support missing fp and 64-bit functionality. Ticket #3029. (CVS 6250)
