Data.Geo.Jord.Length
Description
Types and functions for working with (signed) lengths in metres, kilometres, nautical miles or feet.
In order to use this module you should start with the following imports:
import Data.Geo.Jord.Length (Length) import qualified Data.Geo.Jord.Length as Length
Synopsis
- data Length
- feet :: Double -> Length
- kilometres :: Double -> Length
- metres :: Double -> Length
- nauticalMiles :: Double -> Length
- length :: ReadP Length
- read :: String -> Maybe Length
- toFeet :: Length -> Double
- toKilometres :: Length -> Double
- toMetres :: Length -> Double
- toMillimetres :: Length -> Double
- toNauticalMiles :: Length -> Double
- add :: Length -> Length -> Length
- subtract :: Length -> Length -> Length
- zero :: Length
The Length type
A length with a resolution of 1 micrometre.
Smart constructors
Read
length :: ReadP Length Source #
Parses and returns a Length formatted as (-)float[m|km|nm|ft].
e.g. 3000m, 2.5km, -154nm or 10000ft.
Conversions
toKilometres :: Length -> Double Source #
toKilometres l converts l to kilometres.
toMillimetres :: Length -> Double Source #
toMillimetres l converts l to millimetres.
toNauticalMiles :: Length -> Double Source #
toNauticalMiles l converts l to nautical miles.
