## ST_Angle_Sphere
### description
#### Syntax

`DOUBLE ST_Angle_Sphere(DOUBLE x_lng, DOUBLE x_lat, DOUBLE y_lng, DOUBLE y_lat)`


Calculates the central angle between two points on the Earth's surface. The incoming parameters are the longitude of point X, the latitude of point X, the longitude of point Y and the latitude of point Y.

x_lng and y_lng are Longitude values, must be in the range [-180, 180].
x_lat and y_lat are Latitude values, must be in the range [-90, 90].
