There be many a [http://talklikeapirate.com/wordpress/how-to/ land lubber] that knows [https://dictionary.cambridge.org/dictionary/english/naught naught] of the pirate ways and gives direction by degree! They know not how to [[wp:Boxing the compass|box the compass]]!

# Use the function to print and display a table of Index, Compass point, and Degree; rather like the corresponding columns from, the first table of the [[wp:Boxing the compass|wikipedia article]], but use only the following 33 headings as input:

:`[0.0, 16.87, 16.88, 33.75, 50.62, 50.63, 67.5, 84.37, 84.38, 101.25, 118.12, 118.13, 135.0, 151.87, 151.88, 168.75, 185.62, 185.63, 202.5, 219.37, 219.38, 236.25, 253.12, 253.13, 270.0, 286.87, 286.88, 303.75, 320.62, 320.63, 337.5, 354.37, 354.38]`. (They should give the same order of points but are spread throughout the ranges of acceptance).

;Notes;

• The headings and indices can be calculated from this pseudocode:
```for i in 0..32 inclusive:
case i %3:
if 1: heading += 5.62; break
if 2: heading -= 5.62; break
end
index = ( i mod 32) + 1
```
• The column of indices can be thought of as an enumeration of the thirty two cardinal points (see [[Talk:Box the compass#Direction, index, and angle|talk page]])..

## C

Like [[wp:Box the compass|Wikipedia's article]], this program uses indexes to count the headings. There are now 33 headings, from 1 to 33, because 0.0 and 354.38 are different angles. (This differs from the task pseudocode, which mapped the 32 compass points to indexes.)

```#include <stdio.h>

int main()
{
int i, j;
double degrees[] = { 0.0, 16.87, 16.88, 33.75, 50.62, 50.63, 67.5,

168.75, 185.62, 185.63, 202.5, 219.37, 219.38, 236.25, 253.12,
253.13, 270.0, 286.87, 286.88, 303.75, 320.62, 320.63, 337.5,
354.37, 354.38 };

for (i = 0; i < 33; i++) {

printf("%2d  %.22s  %6.2f\n", (j % 32) + 1, names + (j % 32) * 22,
degrees[i]);
}

return 0;
}

### ES5

An iterative, web-based approach:

```function createRow(i, point, heading) {
var tr = document.createElement('tr'),
td;

td = document.createElement('td');
td.appendChild(document.createTextNode(i));
tr.appendChild(td);

td = document.createElement('td');
point = point.substr(0, 1).toUpperCase() + point.substr(1);
td.appendChild(document.createTextNode(point));
tr.appendChild(td);

td = document.createElement('td');
tr.appendChild(td);

return tr;
}

function getPoint(i) {
var j = i % 8,
i = Math.floor(i / 8) % 4,
cardinal = ['north', 'east', 'south', 'west'],
pointDesc = ['1', '1 by 2', '1-C', 'C by 1', 'C', 'C by 2', '2-C', '2 by 1'],
str1, str2, strC;

str1 = cardinal[i];
str2 = cardinal[(i + 1) % 4];
strC = (str1 === 'north' || str1 === 'south') ? str1 + str2 : str2 + str1;
return pointDesc[j].replace('1', str1).replace('2', str2).replace('C', strC);
}

var i,
table = document.createElement('table'),
tbody = document.createElement('tbody'),
tr;
for (i = 0; i <= 32; i += 1) {
heading = i * 11.25 + [0, 5.62, -5.62][i % 3];
tr = createRow(i % 32 + 1, getPoint(i), heading + '°');
tbody.appendChild(tr);
}
table.appendChild(tbody);
document.body.appendChild(table);

```

## Phix

Unlike the Perl guy, for me the maths is the boring bit, building those strings is the fun!

```Phix
function get225(integer d, string p1, string p2, string p4)
string p3
p3 = p1&'-'&lower(p2)
p2 &= " by "&lower(p1)
p1 &= " by "&lower(p4)
if d then
return {p1,p3,p2}       -- eg {North by east,North-northeast,Northeast by north}
else
return {p2,p3,p1}       -- eg {Northeast by east,East-northeast,East by north}
end if
end function

function get45(sequence res, integer d, string p1, string p2)
string p3
res = append(res,p1)        -- North/East/South/West
if d then
p3 = p1&lower(p2)       -- Northeast/Southwest
else
p3 = p2&lower(p1)       -- Southeast/Northwest
end if
res &= get225(1,p1,p3,p2)   -- eg get225(1,North,Northeast,East)
-- -> {North by east,North-northeast,Northeast by north}
res = append(res,p3)        -- Northeast/Southeast/Southwest/Northwest
res &= get225(0,p2,p3,p1)   -- eg get225(0,East,Northeast,North)
-- -> {Northeast by east,East-northeast,East by north}
return res
end function

function get90(sequence points)
sequence res = {}
for i=1 to length(points) do
res = get45(res,remainder(i,2),points[i],points[remainder(i,4)+1])
end for -- ie get45(1,North,East)
--    get45(0,East,South)
--    get45(1,South,West)
--    get45(0,West,North)
return res
end function

constant compass_points = get90({"North","East","South","West"})

atom test_point
integer compass_point
for i = 1 to 33 do
test_point = (i-1)*11.25 + 5.62*(remainder(i,3)-1)
compass_point = remainder(floor(test_point*32/360+0.5),32)+1
printf(1, "%2d  %-22s  %6.2f\n", {compass_point, compass_points[compass_point], test_point})
end for
```

If you like, you can regard d=1 (both of them) as "clockwise-name-inherit" and d=0 as "anti-clockwise-name-inherit".

resolveindex(Angle, Index) :- N is Angle / 11.25 + 0.5, I is floor(N),Index is (I mod 32) + 1.

```

Part 2 : The following rules print a table of indexes.

```prolog

printTableRow(Angle) :- compassangle(Index, Name, _, Angle),
write(Index), write('    '),
write(Name), write('   '),
write(Angle).

printTable([X|Xs]) :- printTableRow(X), nl, printTable(Xs),!.
printTable([]).

```

The following query prints the required table.

```prolog

## REXX
