Tired of forever converting back and forwards between degrees and radians? Well worry no more; Angle is here to make your life simple!
Angle defines the ~a
sigil so that you can create an Angle easily.
Creating an Angle from decimal degrees:
iex> use Angle
...> ~a(13.2)d
#Angle<13.2°>
Creating an Angle from radians:
iex> use Angle
...> ~a(0.25)r
#Angle<0.25㎭>
Creating an Angle from gradians:
iex> use Angle
...> ~a(40)g
#Angle<40ᵍ>
Create an Angle from degrees, minutes and seconds:
iex> use Angle
...> ~a(90,30,50)dms
#Angle<90° 30′ 50″>
Most functions in Angle return a potentially modified version of the angle, so that if the angle needs to be converted to radians or degrees for the underlying function to work, then it'll only be done once.
Returning the radian representation of an angle
iex> use Angle
...> ~a(13)d
...> |> Angle.to_radians()
...> |> inspect()
"{#Angle<13°>, 0.22689280275926282}"
Angle is available in Hex, the package can be installed
by adding angle
to your list of dependencies in mix.exs
:
def deps do
[
{:angle, "~> 1.0.1"}
]
end
Documentation for the latest release can be found on
HexDocs and for the main
