So 1,729,729 would be one million, seven hundred twenty-nine thousand, seven hundred and twenty-nine.
I would pronounce it the same, but with an 'and' before each instance of 'twenty-nine'.
1,100,000 = one million and one hundred thousand (not sure here).
No 'and' here. The 'bc' components are both '00', so it's simply pronounced 'one million one hundred thousand'. (At least, that's how I pronounce it.)
1,000,200 = one million two hundred (sounds right to me).
Agreed. On Mon, Sep 26, 2011 at 2:17 PM, Adam P. Goucher <apgoucher@gmx.com> wrote:
I think that the rule is to separate a number into the form:
abc [...] abc abc abc
and use the word 'and' before every non-zero 'bc' component.
Examples:
1024: One thousand and twenty-four. 1729: One thousand, seven hundred and twenty-nine. 3600: Three thousand, six hundred. 1000001: One million and one.

I have found some folks over on math-fun who have encountered "and" when spelling out (or I guess speaking) names of numbers over 1000. Also a lot of disagreement to my claim that commas should be written in the same places where the comma would appear in the digits version.
But no-one is giving specific rules (yet :-) and I've spent a while looking but haven't found any rules myself. (Just isolated examples without explanation)
So here are some questions for our colleagues who speak the word "and" as part of a number name -- and regarding the comma, consider how you would write it out in words:
* Do you ever or always use "and" after a power of 1000 if something else follows? ("one million and thirty thousand")
* Do you ever or always use "and" in places where there would be a comma in the digits? ("five thousand three hundred forty seven" but "twelve thousand and three hundred forty seven")
* Or instead of "and" would you put a comma in the words? ("twelve thousand, three hundred forty seven")
* Do you use "and" wherever there are 0s between digits? ("one hundred and seven")
* Do you do two or more of the above? ("five thousand and one hundred and one" or maybe "five thousand, one hundred and one")
* Do you put "and" anywhere else? ("three hundred and forty seven")
* Does it matter how many syllables the part after "and" has? ("one thousand and twelve" but "one thousand seventy-seven")
* Other rules?
* If you consider it proper usage in only part of the English speaking world (like the UK, Australia, Canada, U.S. etc.) let me know that too.
It would be nice to formalize this, because it is used a lot, and almost everything else in OEIS never uses "and", and is mute on commas.
I found 7 OEIS sequences where it is clear if they use "and" or not, there might be more...
A005589 includes a PARI program which gives A005589(1000)=11 and A005589(1001)=14. A052360 has the same program. A052363 agrees with A005589 and A052360 because it includes 1103 but not 1077. A058230 specifically claims "not to put the word 'and' in the names of numbers" A092320 agrees because it contains 1005. A134629 uses Noll's program. [1]
*but* A126259 uses "and" in its spelling of 108

On the program cartalk last week, there was a puzzle of the following form: A list of numbers was given, and one was asked what they had in common (I give the actual puzzler at the end). The answer was that each of these numbers was divisible by the number of letters (excluding spaces) in the standard spelling out of the number in words. This got me to thinking of the following modification: [...] (there followed speculation about A092320 vs. A126259)
