包路径：com.mapbox.geojson.Point
类名称：Point
方法名：longitude

Point.longitude介绍

[英]This returns a double value ranging from -180 to 180 representing the x or easting position of this point. ideally, this value would be restricted to 6 decimal places to correctly follow the GeoJson spec.
[中]这将返回一个介于-180到180之间的双精度值，表示该点的x或东距位置。理想情况下，该值应限制为6位小数，以正确遵循GeoJson规范。
