The naming system comes from Conway (yes, the Game of Life one) and Guy's The Book of Numbers, and it's infinitely extended past 999 using "illi".

      ones       tens                  hundreds          
  1   un         (n)deci               (nx)centi         
  2   duo        (ms)viginti           (n)ducenti        
  3   tre( s)    (ns)trigint(ai)       (ns)trecenti      
  4   quattuor   (ns)quadragint(ai)    (ns)quadringenti  
  5   quinqua    (ns)quinquagint(ai)   (ns)quingenti     
  6   se(sx)     (n)sexagint(ai)       (n)sescenti       
  7   septe( n)  (n)septuagint(ai)     (n)septingenti    
  8   octo       (mx)octogint(ai)      (mx)octingenti    
  9   nove( n)   nonagint(ai)          nongenti

The (letters) at the end of the parts in the ones column get added depending on the (letters) at the beginning of the column it combines with.

undecillion

tredecillion treSvigintillion treStrecentillion

septeNquingentillion septenongentillion

novenonagintillion

The (letters) at the ends of the tens column parts are different.

If there is a hundreds part afterwards an "a" will be used, if there isn't then an "i" will be used. "deci" and "viginti" are the exceptions to this and always use "i".

It also supports JS expressions with a warning before running them.

As a bonus I generated a 500MB file of the number names in order separated by line breaks.
