About:

Magnitude is a library for computing with numbers with
units::

  >>> print "10 m/s ** 2 ->", mg(10, 'm/s') ** 2
  10 m/s ** 2 -> 100.0000 m2 / s2
  >>> print (mg(10, 'm') * 2 / (10, 'm/s2')).sqrt()
  1.4142 s
  >>> tsq = mg(10, 'm') * 2 / (10, 'm/s2')
  >>> print tsq ** 0.5
  1.4142 s
  >>> print mg(1, "lightyear") / mg(1, "c")
  >>> 31557600.0000 s
  >>> y = mg(1, "lightyear") / (1, "c")
  >>> y.ounit("year")
  <magnitude.magnitude instance at 0x81440>
  >>> print y
  1.0000 year
  >>> yd = y.ounit('day')
  >>> print yd
  365.2500 day
  >>> output_precision(0)
  0
  >>> print yd
  365 day
