That's what comparison operators > use, just look at the code. Yes, but the result differs when comparison is done as expression. (e.g. if (expression)) I haven't look into this issue carefully yet, but simple test codes revel the difference. I guess engine is converting values in expression according to context, but not in min(). That's the reason why (expression) and min() result differs, I suppose. I would say it's a bug of min() calling compare_function() as it is now. Regards, -- Yasuo Ohgaki yohgaki@ohgaki.net
