Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: puredata Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Hans-Christoph Steiner (eighthave) Assigned to: Nobody/Anonymous (nobody) Summary: [change] lets some duplicates thru Initial Comment: Sometimes some duplicates get through [change] since it is doing a != for the comparison. Instead it should do a comparison with a set precision, something like this: http://howto.wikia.com/wiki/Howto_compare_float_numbers_in_the_C_programming_language //compares if the float f1 is equal with f2 and returns 1 if true and 0 if false int compare_float(float f1, float f2) { float precision = 0.00001; if (((f1 - precision) < f2) && ((f1 + precision) > f2)) { return 1; } else { return 0; } } ---------------------------------------------------------------------- >Comment By: IOhannes m zmlnig (zmoelnig) Date: 2008-07-23 09:26 Message: Logged In: YES user_id=564396 Originator: NO do you have a practical example that exposes the bug? in theory you are of course right, but in practice i wonder how this can be applied to [change]. e.g. if i send "1" and the result of "2/2" to change, i might consider these two as different enough :-) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1996275&group_id=55736 _______________________________________________ Pd-dev mailing list [email protected] http://lists.puredata.info/listinfo/pd-dev
