Rounds Src object elements [SrcIndex]..[SrcIndex+Len-1] towards negative infinity and stores the result in the calling object elements [Index]..[Index+Len-1].

Pascal
function Floor(const Src: TMtxVec; SrcIndex: integer; Index: integer; Len: integer): TMtxVec; overload;

Size and Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
