 ````geojson```` is a valid GeoJSON object, and can be of type ````Point````, ````LineString````, ````Polygon````, ````MultiPoint````, ````MultiPolygon````, ````MultiLineString````, ````GeometryCollection````, ````Feature````, or ````FeatureCollection````. If you are unsure whether or not your GeoJSON object is valid, you can run it through a linter such as [geojsonhint](https://github.com/mapbox/geojsonhint).
 
-````precision```` is a positive integer. If your specified ````precision```` value is greater than the precision of the input geometry, the output precision will be the same as the input. For example, if your input coordinates are ````[10.0, 20.0]````, and you specify a ````precision```` of ````5````, the output will be the same as the input.
