# ST_EqualsExact

Introduction: Returns true if A and B have the same structure and their corresponding coordinates are equal within a tolerance.

Unlike `ST_Equals`, this predicate requires geometry types, component order, ring order, and vertex order to match. The tolerance is the maximum distance allowed between each pair of corresponding coordinates. The comparison uses x and y coordinates and ignores Z and M coordinates.

Format: `ST_EqualsExact (A: Geometry, B: Geometry, tolerance: Double)`

Return type: `Boolean`

Since: `v1.9.1`

SQL Example

```sql
SELECT ST_EqualsExact(
    ST_GeomFromWKT('POINT (0 0)'),
    ST_GeomFromWKT('POINT (0.03 0.04)'),
    0.05
)
```

Output:

```
true
```

The order of coordinates must match:

```sql
SELECT ST_EqualsExact(
    ST_GeomFromWKT('LINESTRING (0 0, 1 1)'),
    ST_GeomFromWKT('LINESTRING (1 1, 0 0)'),
    0.0
)
```

Output:

```
false
```
