In effetti, non esiste affatto un built-in per la visualizzazione del numero. Sono ancora insoddisfatto del punteggio. Sentiti libero di commentare. Sperimenterò ulteriormente, però. Tuttavia il punteggio è migliore del punteggio di Swift

 c n|n<0=8+c(-n)|n>999=r 1000+8|n>99=7+r 100|n>19=r 10+2-g[30..59]+g[20..29]|n>15=r 10-1|2>1=[0,3,3,5,4,4,3,5,5,4,3,6,6,8,8,7]!!n where{g=fromEnum.elem n;r k=c(mod n k)+c(div n k)} m 4="4 is the magic number" m 0="0 is 4 and "++m 4 m n=show n++" is "++show(c n)++" and "++m(c n)

 m 7 "7 is 5 and 5 is 4 and 4 is the magic number" m 999999 "999999 is 50 and 50 is 5 and 5 is 4 and 4 is the magic number"  

Spiegazione.

m è abbastanza banale, tuttavia, c non lo è. c è la funzione per contare il numero di caratteri del nome inglese di numero.

c n |n<0=8+c(-n) -- Add word "negative" in front of it, the length is 8 |n>999=r 1000+8 -- the english name for number with form xxx,yyy is xxx thousand yyy |n>99=7+r 100 -- the english name for number with form xyy is x hundred yy |n>19=r 10+2-g[30..59]+g[20..29] -- the english name for number with form xy with x more -- than 1 is x-ty. However *twoty>twenty, -- *threety>thirty, *fourty>forty, *fivety>fifty. |n>10=r 10-1-g(15:18:[11..13]) -- the english name for number with form 1x is x-teen. -- However, *oneteen>eleven, *twoteen>twelve, -- *threeteen>thirteen, *fiveteen>fifteen, -- *eightteen>eighteen |2>1=[0,3,3,5,4,4,3,5,5,4,3]!!n -- for number 0-10, the length is memorized. 0 is 0 -- because it is omitted. Input zero is handled -- separately. If we defined 0 to be 4, then -- 20 => twenty zero. where g =fromEnum.elem n -- Check if n is element of argument array, if true, 1 else 0 r k=c(mod n k)+c(div n k) -- Obvious.
