## Name

@(box2df,box2df) — Returns `TRUE` if a 2D float precision bounding box (BOX2DF) is contained into another 2D float precision bounding box.

## Synopsis

`boolean @(` box2df A , box2df B `)`;

## Description

The `@` operator returns `TRUE` if the 2D bounding box A is contained into the 2D bounding box B, using float precision. This means that if A (or 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_MakeBox2D(ST_Point(2,2), ST_Point(3,3)) @ ST_MakeBox2D(ST_Point(0,0), ST_Point(5,5)) AS is_contained;

     is_contained
    --------------
     t
    (1 row)
