 ## Geohash
 
-[Geohash](https://en.wikipedia.org/wiki/Geohash) is the geocode system, which subdivides Earth’s surface into buckets of grid shape and encodes each cell into a short string of letters and digits. It is a hierarchical data structure, so the longer is the geohash string, the more precise is the geographic location.

 Encodes latitude and longitude as a [geohash](#geohash)-string.
 
+**Syntax**
+
 ``` sql
 geohashEncode(longitude, latitude, [precision])
 ```
 
 **Input values**
 
-- longitude - longitude part of the coordinate you want to encode. Floating in range`[-180°, 180°]`
-- latitude - latitude part of the coordinate you want to encode. Floating in range `[-90°, 90°]`
-- precision - Optional, length of the resulting encoded string, defaults to `12`. Integer in range `[1, 12]`. Any value less than `1` or greater than `12` is silently converted to `12`.
+- `longitude` — Longitude part of the coordinate you want to encode. Floating in range`[-180°, 180°]`. [Float](../../data_types/float.md). 
+- `latitude` — Latitude part of the coordinate you want to encode. Floating in range `[-90°, 90°]`. [Float](../../data_types/float.md).
+- `precision` (optional) — Length of the resulting encoded string. Defaults to `12`. Integer in the range `[1, 12]`. [Int8](../../data-types/int-uint.md).

+:::note
+- All coordinate parameters must be of the same type: either `Float32` or `Float64`.
+- For the `precision` parameter, any value less than `1` or greater than `12` is silently converted to `12`.

 **Returned values**
 
-- alphanumeric `String` of encoded coordinate (modified version of the base32-encoding alphabet is used).
