31 // CurrencyTextBox is similar to `dijit/form/NumberTextBox` but has a few
32 // extra features related to currency:
33 //
34 // 1. After specifying the currency type (american dollars, euros, etc.) it automatically
35 // sets parse/format options such as how many decimal places to show.
36 // 2. The currency mark (dollar sign, euro mark, etc.) is displayed when the field is blurred
37 // but erased during editing, so that the user can just enter a plain number.
