Method: Quantify::Unit::Base#pow

Defined in:
lib/quantify/unit/base_unit.rb

#pow(power) ⇒ Object Also known as: **

Raise a unit to a power. This results in the generation of a compound unit, e.g. m^3.

In the event that the new unit represents a known unit, the non-compound representation is returned (i.e. of the SI or NonSI class).
