Detailed Description

Describe an angle.

This class is an attempt to abstract the degree/radian problem.

EXAMPLES::

    sage: from phystricks.SmallComputations import *
    sage: x=AngleMeasure(value_degree=360)
    sage: print x
    AngleMeasure, degree=360.000000000000,radian=2*pi

Conversions are exact::

    sage: a=AngleMeasure(value_degree=30)
    sage: cos(a.radian)
    1/2*sqrt(3)

You can create a new angle from an old one::

    sage: a=AngleMeasure(value_degree=180)
    sage: b=AngleMeasure(a)
    sage: b.degree
    180

If the numerical approximation of an angle in degree is close to an integer
up to less than 1e-10, we round it.
The reason is that in some case I got as entry such a number : 
-(3.47548077273962e-14)/pi + 360
Then the computation of radian gave 0 and we are left with degree 
around 359.9999 while the radian was rounded to 0.

    sage: a=AngleMeasure(value_degree=-(3.47548077273962e-14)/pi + 360)
    sage: a.degree
    360
    sage: a.radian
    2*pi
