The above is totally, utterly **wrong** (consider what happens when ``target`` is 0), yet this could easily be overlooked while writing and during code review.\n\nWith anglr, there is a better way:\n\n.. code:: python\n\n    import math\n    from anglr import Angle\n    heading = Angle(get_compass_value())\n    if heading.angle_between(target) <= math.pi / 4:\n        print(\"Facing the target\")\n    else:\n        print(\"Not facing the target\")\n\nMuch better - this will now correctly take modular arithmetic into account when comparing angles.\n\nExamples\n--------\n\nAngle creation:\n\n.. code:: python\n\n    from math import pi\n    from anglr import Angle\n    print(Angle())\n    print(Angle(87 * pi / 2))\n    print(Angle(pi / 2, \"radians\"))\n    print(Angle(Angle(pi / 2, \"radians\"))) # same as above\n    print(Angle(64.2, \"degrees\"))\n    print(Angle(384.9, \"gradians\"))\n    print(Angle(4.5, \"hours\"))\n    print(Angle(203.8, \"arcminutes\"))\n    print(Angle(42352.7, \"arcseconds\"))\n    print(Angle((56, 32), \"vector\")) # angle in standard position - counterclockwise from positive X-axis\n\nAngle conversion:\n\n.. code:: python\n\n    from anglr import Angle\n    x = Angle(58.3)\n    print([x], str(x), x.radians, x.degrees, x.gradians, x.hours, x.arcminutes, x.arcseconds, x.vector, x.x, x.y)\n    print(complex(x))\n    print(float(x))\n    print(int(x))\n    x.radians = pi / 2\n    print(x.dump())\n    x.degrees = 64.2\n    print(x.dump())\n    x.gradians = 384.9\n    print(x.dump())\n    x.hours = 4.5\n    print(x.dump())\n    x.arcminutes = 203.8\n    print(x.dump())\n    x.arcseconds = 42352.7\n    print(x.dump())\n    x.vector = (56, 32)\n    print(x.dump())\n\nAngle arithmetic:\n\n.. code:: python\n\n    from math import pi\n    from anglr import Angle\n    print(Angle(pi / 6) + Angle(2 * pi / 3))\n    print(x * 2 + Angle(3 * pi / 4) / 4 + 5 * Angle(pi / 3))\n    print(-abs(+Angle(pi)))\n    print(round(Angle(-75.87)))\n    print(Angle(-4.3) <= Angle(pi / 4) > Angle(0.118) == Angle(0.118))\n    print(Angle(-870.3, \"gradians\").normalized())\n    print(Angle(-870.3, \"gradians\").normalized(0)) # same as above\n    print(Angle(-870.3, \"gradians\").normalized(0, 2 * pi)) # same as above\n    print(Angle(-870.3, \"gradians\").normalized(-pi, pi))\n    print(Angle(-870.3, \"gradians\").normalized(-pi, 0))\n    print(Angle(1, \"degrees\").angle_between_clockwise(Angle(0, \"degrees\")))\n    print(Angle(1, \"degrees\").angle_between(Angle(0, \"degrees\")))\n    print(Angle(0, \"degrees\").angle_within(Angle(-45, \"degrees\"), Angle(45, \"degrees\")))\n    print(Angle(-1, \"degrees\").angle_within(Angle(-1, \"degrees\"), Angle(1, \"degrees\"), strictly_within=True))\n    print(Angle(-1, \"degrees\").angle_to(Angle(180, \"degrees\")))\n    print(Angle(0, \"degrees\").angle_to(Angle(180, \"degrees\")))\n\nTo run all of the above as tests, simply run ``python3 tests.py`` in the project directory.\n\nInstalling\n----------\n\nThe easiest way to install this is using ``pip3 install anglr``.\n\nOtherwise, download the source distribution from `PyPI <https://pypi.python.org/pypi/anglr/>`__, and extract the archive.\n\nIn the folder, run ``python3 setup.py install``.\n\nRequirements\n------------\n\nThis library requires Python 3.2 or higher to run.\n\nAuthors\n-------\n\n::\n\n    Uberi <azhang9@gmail.com> (Anthony Zhang)\n\nPlease report bugs and suggestions at the `issue tracker <https://github.com/Uberi/anglr/issues>`__!\n\nLicense\n-------\n\nCopyright 2014-2015 `Anthony Zhang (Uberi) <https://uberi.github.io>`__.\n\nThe source code is available online at `GitHub <https://github.com/Uberi/anglr>`__.\n\nThis program is made available under the 3-clause BSD license.
