Most other programming languages don't. There are reasons we use IEEE754: it's fixed-sized, it's built-in pretty > much everywhere, and it's usually implemented in hardware, so it's fast. The IEEE754-2008 standard includes both base 2 (binary) and base 10 (decimal) numbers. E.g., decimal64, decimal128, as well as binary64 (typical C double) and binary32 (typical C float). There are few hardware implementations of decimal floats; modern processors that have it include IBM System Z and POWER6. e _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
