date parameter is a DATE value and your calculation only contains the YEAR, MONTH, and DAY sections (that is, there is no time section), the result is a DATE value. Otherwise, the result is a DATETIME value. Mysql> SELECT "23:59:59" + INTERVAL 1 SECOND;-> 00:00:00 Mysql> select interval 1 DAY + "1997-12-31 "; -> 1998-01-01 Mysql> SELECT "1998-01-01"-INTERVAL 1 SECOND; -> 1997-12-31 23:59:59 Mysql> SELECTDATE_ADD("23:59:59", INTERVAL 1 SECOND ); -> 00

Opencascade Curve Length Calculation [Email protected] Abstract.The natural parametric equations of a curve are parametric equations that represent the curve in terms of a coordinate-independent parameter, generally arc length S, instead of an arbitray variable like T or U. according to the natural equations, the curve length is the integration of the curve parametric equation's derivation. so the Core Algorithm for curve length
