class Numeric

Extend the Numeric class to add a scaling helper. eg: 0.40.scaled_from(0..1).to([512, 128, 64, 32, 16, 12, 8, 4, 2, 0])

This is not included by default with the rest of the library. use require “scale/core_ext”

Public Instance Methods

scaled() click to toggle source

Build a Scheme for this numeric as input. @return [Scale::Scheme]

# File lib/scale/core_ext.rb, line 12
def scaled
  Scale.transform(self)
end

scaled_from(source) click to toggle source

Build a scheme with this numeric as input and add the given source to it. If on calling this method, the scheme has all of its needed properties, the scaled value will be returned. Otherwise # this method will return the updated Scheme object.

@param [Scale::Source] source @return [Numeric, Scale::Scheme]

# File lib/scale/core_ext.rb, line 31
def scaled_from(source)
  Scale.transform(self).from(source)
end

scaled_to(destination) click to toggle source

Build a scheme with this numeric as input and add the given destination to it. If on calling this method, the scheme has all of its needed properties, the scaled value will be returned. Otherwise # this method will return the updated Scheme object.

@param [Scale::Destination] destination @return [Numeric, Scale::Scheme]

# File lib/scale/core_ext.rb, line 42
def scaled_to(destination)
  Scale.transform(self).to(destination)
end

scaled_using(source, destination) click to toggle source

Scale using the given source and destination, with this numeric as input. @param [Scale::Source] source @param [Scale::Destination] destination @return [Numeric]

# File lib/scale/core_ext.rb, line 20
def scaled_using(source, destination)
  Scale.transform(self).using(source, destination)
end
