Amount in words in Google Spreadsheets
Today, implemented in Spreadsheets the function Sum in words , which, I hope, will be useful to the habrasociety as an example. I needed it as a generator of amounts for bills and invoices.
Open the table https://spreadsheets.google.com/ccc?key=0AppCRCbx33I9dG1rM2lmSW56VmFVeVBmZng0dE5jcmc&hl=en
Just copy the table into your account and enter = FloatToSamplesInWordsRus ( A3 ) with a link to the value in the required field.

You can use many ready-made functions and libraries, well, your development, of course.
