Inputs

Name	Type	Description
ipSrcPointsCart	ITcVnContainer	Container with cartesian points (ContainerType_Vector_TcVnPoint2_DINT or ContainerType_Vector_TcVnPoint2_REAL or ContainerType_Vector_TcVnPoint2_LREAL)
ipDestPointsPolar	Reference To ITcVnContainer	Returns a container which is filled with the converted points in polar coordinates (ContainerType_Vector_TcVnPoint2_REAL, if source points are of type TcVnPoint2_DINT or TcVnPoint2_REAL; else ContainerType_Vector_TcVnPoint2_LREAL. Non-zero interface pointers are reused.)
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

Return value

HRESULT
