-- | Library to provide the behaviour similar to quantum states superposition. 
--   
--   Has three modules with similar functionality. The functions provide
--   the somewhat generalized way to round the numbers based on some data.
@package quantizer
@version 0.3.0.2


-- | A module to provide the simple version of the obtaining from the list
--   of values the list of other values, the pre-defined ones. Provides
--   both pure functions and monadic versions. Contrary to ListQuantizer
--   module, the results in every function here depend on the two values,
--   which the point is located in between. Defined for just positive real
--   numbers of <a>Double</a> type.

-- | Simple arithmetic mean. Is vulnerable to floating point rounding error

-- | A module to provide the extended variants to convert a list with some
--   values to another one with the values from the pre-defined another
--   list. Similar to the measurement of the quantum state observables with
--   the discrete spectrum. Contrary to TwoQuantizer module, the results in
--   every function here depend not just on the two values, which the point
--   is located in between, but on the whole list. Defined for just
--   positive real numbers of <a>Double</a> type.
module ListQuantizer

-- | A better suited variant for <a>round2G</a> for lists.

-- | A module to provide the extended variants to convert a
--   <a>InsertLeft</a> instance structure with some values to another one
--   with the values from the pre-defined structure. Similar to the
--   measurement of the quantum state observables with the discrete
--   spectrum. For performance reasons it is better to use module
--   ListQuantizer whenever possible (especially if the given
--   <a>Foldable</a> and <a>InsertLeft</a> instances are just lists).
--   Contrary to TwoQuantizer module, the results in every function here
--   depend not just on the two values, which the point is located in
--   between, but on the whole structure. Defined for just positive real
--   numbers of <a>Double</a> type.
