I have a ToDo item for this probem, but there are complications. The
system you so kindly implemented is definitely the "U.S." system my
research uncovered, but entirely dissimilar to the U.K. system I found.
Here are my notes on the two:
U.S. approach

12 duodecillion
13 tredecillion The latin roots of the numbers show the
14 quattuordecillion # of groups of 3-zeroes that follow 1000.
15 quindecillion 2=bi, 3=tri, 4=quad, 5=quin, 6=sex, 7=sept
16 sexdecillion 8=oct, 9=non, 10=decem, 20=vigin.
17 septendecillion
18 octodecillion Names for groups 3 to 63 come from several
19 novemdecillion sources, both encyclopedic and dictionary.
20 vigintillion
21 unvigintillion Prefixes un-, duo-, tre-, quattuor, quin-,
22 duovigintillion sex-, sept-, octo, and novem-, appear to
23 trevigintillion modify TEN (decem) to make 11 to 19.
24 quattuorvigintillion
25 quinvigintillion I followed the same pattern before
26 sexvigintillion vigintillion to create 21 to 29 sets
27 septenvigintillion of 000's after 1,000.

2. British approach
-------------------
number
of
0's Name samples of some of them
==--======---==================
3 thousand 1,000
6 million 1,000,000
9 milliard 1,000,000,000
12 billion 1,000,000,000,000
15 billiard 1,000,000,000,000,000
18 trillion 1,000,000,000,000,000,000
21 trilliard 1,000,000,000,000,000,000,000
24 quadrillion 1,000,000,000,000,000,000,000,000
27 quadrilliard 1,000,000,000,000,000,000,000,000,000
30 quintillion 1,000,000,000,000,000,000,000,000,000,000
33 quintilliard 1,000,000,000,000,000,000,000,000,000,000,000
36 sextillion 1,000,000,000,000,000,000,000,000,000,000,000,000
39 sextilliard
42 septillion NOTE that if you divide the # of zeroes by six,
45 septilliard you have the number that relates to the word of
48 octillion the group. 2=bi, 3=tri, 4=quad, 5=quin, 6=sex,
51 octilliard 7=sept, 8=oct, 9=non, 10=decem, 20=viginti.
54 nonillion
57 nonilliard the names for number groups
60 decillion (TEN) 3, 6, 9, 12, and every multiple
63 decilliard of 6 up to 120 came from
66 undecillion several sources, both dictionary
69 undecilliard and encyclopedic.
72 duodecillion
75 duodecilliard I followed the pattern of
78 tredecillion "million" to "milliard" to list
81 tredecilliard all other groups up to 123.
84 quattuordecillion
87 quattuordecilliard The prefixes un-, duo-, tre-, quattuor-,
90 quindecillion quin-, sex-, septen, octo-, and novem-
93 quindecilliard appear to modify the latin TEN (decem),
96 sexdecillion to make 11, 12, up to 19.
99 sexdecilliard
102 septendecillion
105 septendecilliard
108 octodecillion
111 octodecilliard
114 novemdecillion
117 novemdecilliard
120 vigintillion (TWENTY)
123 vigintilliard
126 unvigintillion I followed the prefix-pattern
129 unvigintilliard used before -decillion and
132 duovigintillion -decilliard to create the names
135 duovigintilliard for 126 to 177, 21 through 29
138 trevigintillion groups of six.
141 trevigintilliard
144 quattuorvigintillion
147 quattuorvigintilliard
150 quinvigintillion
153 quinvigintilliard
156 sexvigintillion
159 sexvigintilliard
162 septenvigintillion
165 septenvigintilliard
168 octovigintillion
171 octovigintilliard
174 novemvigintillion
177 novemvigintilliard
you can figure out the names are for 180 through 597 zeroes
by looking at the list for American Numbering System.
180, 186, 192 ...: Divide the number by 6, use that name.
183, 189, 195 ...: Change the name for 3 less.
600 centillion
603 centilliard? (absolute guess, not found in any source).
When I get around to implementing this extension, I will probably default
to the U.S. approach (which seems to be gaining popularity) and add an
extra flag to request the U.K. system instead.
Thanks again for all your excellent feedback and suggestions,
Damian
