Module: RichUnits::Multiplers::Numeric

Included in:
Numeric
Defined in:
lib/richunits/multipliers.rb

Overview

Numeric Multipliers

Adds methods to Numeric to make working with magnitudes (kilo, mega, giga, milli, micro, etc.) as well as bits and bytes easier.

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
