Task
Price fraction
You are encouraged to solve this task according to the task description, using any language you may know.

A friend of mine runs a Pharmacy. He has a specialised function in his Dispensary application which receives a decimal value of currency and replaces it to a standard value. This value is regulated by a government department.

Task: Given a floating point value between 0.00 and 1.00, rescale according to the following table:

>=  0.00  <  0.06  :=  0.10
>=  0.06  <  0.11  :=  0.18
>=  0.11  <  0.16  :=  0.26
>=  0.16  <  0.21  :=  0.32
>=  0.21  <  0.26  :=  0.38
>=  0.26  <  0.31  :=  0.44
>=  0.31  <  0.36  :=  0.50
>=  0.36  <  0.41  :=  0.54
>=  0.41  <  0.46  :=  0.58
>=  0.46  <  0.51  :=  0.62
>=  0.51  <  0.56  :=  0.66
>=  0.56  <  0.61  :=  0.70
>=  0.61  <  0.66  :=  0.74
>=  0.66  <  0.71  :=  0.78
>=  0.71  <  0.76  :=  0.82
>=  0.76  <  0.81  :=  0.86
>=  0.81  <  0.86  :=  0.90
>=  0.86  <  0.91  :=  0.94
>=  0.91  <  0.96  :=  0.98
>=  0.96  <  1.01  :=  1.00

Ada

<lang Ada> type Price is delta 0.01 digits 3 range 0.0..1.0; function Scale (Value : Price) return Price is

  X : constant array (1..19) of Price :=
         (  0.06, 0.11, 0.16, 0.21, 0.26,  0.31, 0.36, 0.41, 0.46, 0.51,
            0.56, 0.61, 0.66, 0.71, 0.76,  0.81, 0.86, 0.91, 0.96
         );
  Y : constant array (1..20) of Price :=
         (  0.10, 0.18, 0.26, 0.32, 0.38,  0.44, 0.50, 0.54, 0.58, 0.62,
            0.66, 0.70, 0.74, 0.78, 0.82,  0.86, 0.90, 0.94, 0.98, 1.0
         );
  Low    : Natural := X'First;
  High   : Natural := X'Last;
  Middle : Natural;

begin

  loop
     Middle := (Low + High) / 2;
     if Value = X (Middle) then
        return Y (Middle + 1);
     elsif Value < X (Middle) then
        if Low = Middle then
           return Y (Low);
        end if;
        High := Middle - 1;
     else
        if High = Middle then
           return Y (High + 1);
        end if;
        Low := Middle + 1;
     end if;
  end loop;

end Scale; </lang> The solution uses fixed point type to prevent rounding and representation issues. With the above declarations a full coverage test: <lang Ada> with Ada.Text_IO; use Ada.Text_IO; procedure Test_Price_Fraction is

  -- Put the declarations here
  Value : Price := Price'First;

begin

  loop
     Put_Line (Price'Image (Value) & "->" & Price'Image (Scale (Value)));
     exit when Value = Price'Last;
     Value := Price'Succ (Value);
  end loop;

end Test_Price_Fraction; </lang> Sample output:

Works with: QBasic

This could also be done by building an array, but I felt that this was simpler.

<lang qbasic>DECLARE FUNCTION PriceFraction! (price AS SINGLE)

RANDOMIZE TIMER DIM x AS SINGLE x = RND PRINT x, PriceFraction(x)

FUNCTION PriceFraction! (price AS SINGLE)

   'returns price unchanged if invalid value
   SELECT CASE price
       CASE IS < 0!
           PriceFraction! = price
       CASE IS < .06
           PriceFraction! = .1
       CASE IS < .11
           PriceFraction! = .18
       CASE IS < .16
           PriceFraction! = .26
       CASE IS < .21
           PriceFraction! = .32
       CASE IS < .26
           PriceFraction! = .38
       CASE IS < .31
           PriceFraction! = .44
       CASE IS < .36
           PriceFraction! = .5
       CASE IS < .41
           PriceFraction! = .54
       CASE IS < .46
           PriceFraction! = .58
       CASE IS < .51
           PriceFraction! = .62
       CASE IS < .56
           PriceFraction! = .66
       CASE IS < .61
           PriceFraction! = .7

Forth

A floating-point version wouldn't be hard -- four words would change ( , @ @ cell+ -to- f, f@ f@ float+ ), EVALUATE would be replaced with a small word that forced a floating-point interpretation, and the return stack would not be used in ROUND -- but it would be strikingly unusual.

This implementation performs a binary search on the boundary values, and then uses the resulting index to select from the result values.

To prevent J's binary search from doing the wrong thing for values equal to a boundary, both the boundary values and the search value are negated.

say price($value);

sub price($value) { for $table.lines -> $line { $line ~~ / '>=' \s+ (\S+) \s+ '<' \s+ (\S+) \s+ ':=' \s+ (\S+)/; return $2 if $0 <= $value < $1; } fail "Out of range"; }</lang> Perhaps a better approach is just to build an array of 101 entries. Memory is cheap, and array lookup is blazing fast, especially important if used in a loop as below. Moreover, in Perl 6 we don't have to worry about floating point misrepresentations of decimals because decimal fractions are stored as rationals.

<lang perl6>my @price = map *.value,

   ( 0 ..^ 6  X=> 0.10),
   ( 6 ..^ 11 X=> 0.18),
   (11 ..^ 16 X=> 0.26),
   (16 ..^ 21 X=> 0.32),
   (21 ..^ 26 X=> 0.38),
   (26 ..^ 31 X=> 0.44),
   (31 ..^ 36 X=> 0.50),
   (36 ..^ 41 X=> 0.54),
   (41 ..^ 46 X=> 0.58),
   (46 ..^ 51 X=> 0.62),
   (51 ..^ 56 X=> 0.66),
   (56 ..^ 61 X=> 0.70),
   (61 ..^ 66 X=> 0.74),
   (66 ..^ 71 X=> 0.78),
   (71 ..^ 76 X=> 0.82),
   (76 ..^ 81 X=> 0.86),
   (81 ..^ 86 X=> 0.90),
   (86 ..^ 91 X=> 0.94),
   (91 ..^ 96 X=> 0.98),
   (96 ..^101 X=> 1.00),

while prompt("value: ") -> $value {

   say @price[ $value * 100 ] // note "Out of range";

}</lang>

Yet another approach is to use the conditional operator to encode the table. This allows each endpoint to be written once, avoiding duplication. <lang perl6>sub price_fraction ( Num $n where { $^n >= 0 and $^n <= 1 } ) {

      ( $n <  0.06 ) ?? 0.10

Python

Using the bisect standard module to reduce the comparisons with members of the cin array.

<lang python>>>> import bisect >>> _cin = [.06, .11, .16, .21, .26, .31, .36, .41, .46, .51, .56, .61, .66, .71, .76, .81, .86, .91, .96, 1.01] >>> _cout = [.10, .18, .26, .32, .38, .44, .50, .54, .58, .62, .66, .70, .74, .78, .82, .86, .90, .94, .98, 1.00] >>> def pricerounder(pricein): return _cout[ bisect.bisect_right(_cin, pricein) ]</lang>

When dealing with money it is good to think about possible loss of precision. If we change the units to be integer cents we could use the following exact routine: <lang python>>>> import bisect >>> _cin = [ 6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 71, 76, 81, 86, 91, 96, 101] >>> _cout = [10, 18, 26, 32, 38, 44, 50, 54, 57, 62, 66, 70, 74, 78, 82, 86, 90, 94, 98, 100] >>> def centsrounder(centsin): return _cout[ bisect.bisect_right(_cin, centsin) ]</lang> Other options are to use the fractions or decimals modules for calculating money to a known precision.


Bisection library code

The bisect Python standard library function uses the following code that improves on a simple linear scan through a sorted list:
<lang python>def bisect_right(a, x, lo=0, hi=None):
   """Return the index where to insert item x in list a, assuming a is sorted.
   The return value i is such that all e in a[:i] have e <= x, and all e in
   a[i:] have e > x.  So if x already appears in the list, a.insert(x) will
   insert just after the rightmost x already there.
   Optional args lo (default 0) and hi (default len(a)) bound the
   slice of a to be searched.
   """
   if lo < 0:
       raise ValueError('lo must be non-negative')
   if hi is None:
       hi = len(a)
   while lo < hi:
       mid = (lo+hi)//2
       if x < a[mid]: hi = mid
       else: lo = mid+1
   return lo</lang>

R

<lang r> price_fraction <- function(x) {

 stopifnot(all(x >= 0 & x <= 1))
 breaks <- seq(0.06, 1.01, 0.05)
 values <- c(.1, .18, .26, .32, .38, .44, .5, .54, .58, .62, .66, .7, .74, .78, .82, .86, .9, .94, .98, 1)
 indices <- sapply(x, function(x) which(x < breaks)[1])
 values[indices]

}

  1. Example usage:

price_fraction(c(0, .01, 0.06, 0.25, 1)) # 0.10 0.10 0.18 0.38 1.00 </lang>

You can extract the contents of the table as follows:

<lang r> dfr <- read.table(tc <- textConnection( ">= 0.00 < 0.06  := 0.10 >= 0.06 < 0.11  := 0.18 >= 0.11 < 0.16  := 0.26 >= 0.16 < 0.21  := 0.32 >= 0.21 < 0.26  := 0.38 >= 0.26 < 0.31  := 0.44 >= 0.31 < 0.36  := 0.50 >= 0.36 < 0.41  := 0.54 >= 0.41 < 0.46  := 0.58 >= 0.46 < 0.51  := 0.62 >= 0.51 < 0.56  := 0.66 >= 0.56 < 0.61  := 0.70 >= 0.61 < 0.66  := 0.74 >= 0.66 < 0.71  := 0.78 >= 0.71 < 0.76  := 0.82 >= 0.76 < 0.81  := 0.86 >= 0.81 < 0.86  := 0.90 >= 0.86 < 0.91  := 0.94 >= 0.91 < 0.96  := 0.98 >= 0.96 < 1.01  := 1.00")); close(tc) breaks <- dfr$V4 values <- dfr$V6 </lang>

Ruby

A simple function with hardcoded values. <lang ruby>def rescale_price_fraction(value)

 raise ArgumentError, "value=#{value}, must have: 0 <= value < 1.01" if value < 0 || value >= 1.01
 if     value < 0.06  then  0.10
 elsif  value < 0.11  then  0.18
 elsif  value < 0.16  then  0.26
 elsif  value < 0.21  then  0.32
 elsif  value < 0.26  then  0.38
 elsif  value < 0.31  then  0.44
 elsif  value < 0.36  then  0.50
 elsif  value < 0.41  then  0.54
 elsif  value < 0.46  then  0.58
 elsif  value < 0.51  then  0.62
 elsif  value < 0.56  then  0.66
 elsif  value < 0.61  then  0.70
 elsif  value < 0.66  then  0.74
 elsif  value < 0.71  then  0.78
 elsif  value < 0.76  then  0.82
 elsif  value < 0.81  then  0.86
 elsif  value < 0.86  then  0.90
 elsif  value < 0.91  then  0.94
 elsif  value < 0.96  then  0.98
 elsif  value < 1.01  then  1.00
 end

Tcl

Structured as two functions, one to parse the input data as described in the problem into a form which Tcl can work with easily, and the other to perform the mapping. <lang tcl># Used once to turn the table into a "nice" form proc parseTable table {

   set map {}
   set LINE_RE {^ *>= *([0-9.]+) *< *([0-9.]+) *:= *([0-9.]+) *$}
   foreach line [split $table \n] {

if {[string trim $line] eq ""} continue if {[regexp $LINE_RE $line -> min max target]} { lappend map $min $max $target } else { error "invalid table format: $line" }

   }
   return $map

}

  1. How to apply the "nice" table to a particular value

proc priceFraction {map value} {

   foreach {minimum maximum target} $map {

if {$value >= $minimum && $value < $maximum} {return $target}

   }
   # Failed to map; return the input
   return $value

}</lang> How it is used: <lang tcl># Make the mapping set inputTable {

  • ~&p(le,out) zips the pair of lists le and out into a list of pairs
  • A function of the form f\y applied to an argument x evaluates to f(x,y)
  • A function of the form f*| applied to a pair (x,y) where y is a list, makes a list of pairs with x on the left of each item and an item of y on the right. Then it applies f to each pair, makes a list of the right sides of those for which f returned true, and makes a separate list of the right sides of those for which f returned false.
  • The suffix rhr after the *| operator extracts the right side of the head of the right list from the result.
  • The operand to the *| operator, fleq@rlPlX is the less-or-equal predicate on floating point numbers, composed with the function ~&rlPlX which transforms a triple (u,(v,w)) to (v,u)
