Name

contained into a 2D float precision bounding box (BOX2DF).
Description
The @ operator returns TRUE if the A geometry’s 2D bounding box
is contained the 2D bounding box B, using float precision. This means
that if B is a (double precision) box2d, it will be internally converted
to a float precision 2D bounding box (BOX2DF)
