<div><p>Translates numeric input to a text string.</div>
<div><p><code>ft_NToW()</code> is intended to be used with integers only. Since I don't know what your application will be, I cannot assume the type of fraction you want returned (ninety nine cents, 99/100, .99, etc). If you want the fraction in words, just pass it as an integer.</div>
<div><p>Do not pass a negative number! Handle negative numbers any way you need to in your code. (i.e.: CR, DB, Negative, Minus, etc.)</div>
<div><p>Also, numeric 0 is returned as a null string. You will need to make a decision how to output it (zero dollars, no dollars, etc).</div>
</div>
