How will American write it?

Answer

Agree with srgause. Here is how I would write it on a check (if only I had $2m to spend!!! ;) )

$2,123,456.78
Two million, one hundred and twenty-three thousand, four hundred and fifty-six and 78/100 US Dollars (or USD)
or ... fifty-six dollars and 78 cents

Answer

117,182.58

Answer

An American would only put the dollar amount on an invoice (using numbers, not words). We write amounts in words on checks, but that is the only time.

Answer

US Dollars Two million one hundred twenty-three thousand four hundred fifty-six and cents seventy-eight only
