Numeric::Multipliers

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.
