Translating numbers into words

Translating numbers into words

(OP)
Hey folks,

We just started with scheme at the university and I need some help doing my task.

We shall write a program that translates numbers into words, e.g 1 to "one". It must work for all numbers up to 10 ^ 9.
I've got no real clue how to do this... My basic idea would be to create some sort of array or list where I define those numbers as words like this:


('ZERO',    0)
('ONE',            1)
('TWO',      2)
('THREE',    3)
('FOUR',    4)
('FIVE',    5)
('SIX',     6)
('SEVEN',    7)
('EIGHT',    8)
('NINE',    9)
('TEN',     10)
('ELEVEN',    11)
('TWELVE',    12)
('THIRTEEN',    13)
('FOURTEEN',    14)
('FIFTEEN',    15)
('SIXTEEN',    16)
('SEVENTEEN',    17)
('EIGHTEEN',    18)
('NINETEEN',    19)
('TWENTY',    20)
('THIRTY',    30)
('FORTY',    40)
('FIFTY',    50)
('SIXTY',    60)
('SEVENTY',    70)
('EIGHTY',    80)
('NINETY',    90)
('HUNDRED',    100)
('THOUSAND',    1000)
('MILLION',     1000000)
('BILLION',     1000000000)
('TRILLION',    1000000000000)
('QUADRILLION', 1000000000000000)

Then somehow check the input value with this list and substitute the numbers with the words. But implementing this is giving me some trouble. Hope someone can help :)

Thats Python though. How does it work in scheme? Apparently the guy has the same idea :D

RE: Translating numbers into words

Recursive method. When do you stop recursion ?
You study (quotient N 1000) and (modulo N 1000).
You must memorize the state (unit, thousand, million ...).
