Show a text field that allows the user to enter dollar amounts including the dollar symbol and thousand separators, but save the value as a decimal rather than text. Additionally, always show the dollar amount with the dollar symbol.
This scenario demonstrates:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 a!localVariables( local!amount, a!textField( label:"Amount in Text", /* Instructions show the saved datatype*/ instructions: "Type of local!amount: " & typename(typeof(local!amount)), value: a!currency( isoCode: "USD", value: local!amount, format: "SYMBOL" ), /* Instead of saving the value as text, a!save() is used to store to the desired datatype*/ saveInto: a!save(local!amount, todecimal(save!value)) ) )
Each of the following examples assumes you have the Locale set to English (US) in your user settings. Try changing your user locale to see how the currency formatting changes.
$12345and click away from the field. Notice that the text box shows $12,345.00 and that the saved value is a decimal.
$12,345.23and click away from the field.
a1b2c3and click away. Notice that the text box removes the non-numeric characters and treats the remaining as a decimal value. A true currency component would catch this as an error case, hence why this is called a simple currency example.
