This form is an example of how you can use a series of complicated XForms calculate binds to convert a number to the word representation. For example, entering 123456.16 would produce " one hundred twenty three thousand four hundred and fifty six dollars and sixteen cents".
The technique used is to evaluate each decimal place in its own bind and then use a bind to build the string. The key words are stored in an instance and then mapped to the decimal place. The only tricky part to the technique is detecting the 11-19 scenario since the words change.
The XPath functions used in this example are:
