## Name

@(geometry,box2df) — Returns `TRUE`

if a geometry's 2D bounding box is contained into a 2D float precision bounding box (BOX2DF).

## Synopsis

`boolean `**@**(

geometry
`A`
,
box2df
`B`
`)`

;

## 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)

This operand is intended to be used internally by BRIN indexes, more
than by users. |

Availability: 2.3.0 support for Block Range INdexes (BRIN) was introduced. Requires PostgreSQL 9.5+.

This method supports Circular Strings and Curves.

This function supports Polyhedral surfaces.

## Examples

SELECT ST_Buffer(ST_GeomFromText('POINT(2 2)'), 1) @ ST_MakeBox2D(ST_Point(0,0), ST_Point(5,5)) AS is_contained;
is_contained
