## Description

Returns the x coordinate of a Point geometry.

## Syntax

MI_X ( point_geometry )

## Arguments

`point_geometry` is an expression which returns a feature geometry of type Point.

## Example

Returns the x coordinate point for the centroid of countries starting with 'bra'.

`select Country,MI_X(MI_Centroid([Geometry_Column])) as MI_X from countries where country like 'bra%'`

## Remarks

The value returned is a double and represents a value in terms of the coordinate system of the input `point_geometry`. If the input geometry is not a Point geometry, then null is returned.
