Bases: astropy.units.function.FunctionQuantity
A representation of a (scaled) logarithm of a number with a unit
Parameters: | value : number, Quantity, LogQuantity, or sequence of convertible items.
unit : string, UnitBase or FunctionUnitBase instance, optional
dtype : dtype, optional
copy : bool, optional

Examples
Typically, use is made of an FunctionQuantity subclasses, as in:
>>> import astropy.units as u
>>> u.Magnitude(15.)
<Magnitude 15.0 mag>
>>> u.Magnitude(10.*u.count/u.second)
<Magnitude -2.5 mag(ct / s)>
>>> u.Decibel(1.*u.W, u.DecibelUnit(u.mW))
<Decibel 30.0 dB(mW)>
