The vast majority of processors implement IEEE754-1985 and have native instructions for doing so. The C compiler typically compiles down to those instructions. IEE754-2008 is a superset of -1985 and only some processors have instructions for it. http://en.wikipedia.org/wiki/IEEE_754-2008 http://en.wikipedia.org/wiki/IEEE_754-1985 Roger -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAksvnegACgkQmOOfHg372QTGIgCgmzX7zZxNpR+AAK0kk0RPmYNY ncMAnRlAei6kwUHgvlRSUDoJayZNpxtq =2Jlc -----END PGP SIGNATURE----- _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
