--   Allows to change the structure of the function output for the

--   basic functions for the filters. Is taken from the
--   uniqueness-periods-vector-filters package that is intended to be
--   rewritten. These functions are basic for it and for its successor,
--   phonetic-languages-filters-array package.

-- | A module allows to change the structure of the function output for the
--   functions of elements from <a>RealFrac</a> class. At the moment only
--   the equal intervals are supported. Has basic functions for the
--   filters. Is taken from the <tt>uniqueness-periods-vector-filters</tt>
--   package that is intended to be rewritten. These functions are basic
--   for it and for its successor,
--   <tt>phonetic-languages-filters-array</tt> package.
module Data.Filters.Basic

-- | Given the minimum and maximum elements, a quantity of equal intervals,
--   and an element in between the first two arguments (or equal to one of
--   them), finds out the index of the interval, to which the element
--   belongs (starting from 1). The minimum element belongs to the interval
--   with the index 1.
intervalNRealFrac :: (RealFrac b, Integral c) => b -> b -> c -> b -> c
zero2One :: Integral a => a -> a

-- | Moves (if needed) the given value so that its result divides the new
--   [min..max] interval in the same proportion as the starting one. Is
--   intended to be used for the arguments satisfying some additional
--   constraints, but they are not checked (hence, its name prefix
--   "unsafe"). For example, the second argument must be greater than the
--   first one, the fourth -- than the third one, and the fifth must be
--   located in between the first two. Then the result is also located in
--   between the third and fourth arguments similarly.
unsafeTransfer1I5 :: RealFrac b => b -> b -> b -> b -> b -> b

-- | A variant of the <a>unsafeTransfer1I5</a> where the lengths of the
--   both intervals (the old and the new ones) are equal.
