class Numeric
# = Numeric::Multipliers
#
# Adds methods to Numeric to make working with
# magnitudes (kilo, mega, giga, milli, micro, etc.)
#
# 1.kilo #=> 1000
# 1.milli #=> 0.001
# 1.kibi #=> 1024
#
# To display a value in a certain denomination, simply
# perform the inverse operation by placing the
# multiplier called on unit (1) in the denominator.
#
# (1000 / 1.kilo) #=> 1
# (1024 / 1.kibi) #=> 1
#
# Thanks to Rich Kilmer and bytes.rb which inspired this library.
