I like the optional second parameter. Apart from the obvious change to likelihood, which somebody else suggested, but which is less self documenting in the one-argument case, I'd suggest that you actually add two words: likely and unlikely, and whose second parameters are the inverse of each other, crossing at 0.5. So an expression could then, in the simplest case, be labeled LIKELY or UNLIKELY, with second parameter defaulting to 1.0 (or to whatever value you feel is appropriate), but allowing the user to specify a lesser likelihood by lowering that value. LIKELY(expr, 0) would mean the same as UNLIKELY(expr) and UNLIKELY(expr, 1), and UNLIKELY(expr, 0) would be the same as LIKELY(expr, 1), etc. James _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
