Choose to round a decimal value that is 3 or more places and return the dollar formatted value.

// Because of https://tracker.adobe.com/#/view/CF-4199995,
// I've come across a few scenarios where dollarFormat() and numberFormat() will not round up when expected/desired.
// Looking at how Java handles BigDecimals and rounding them, it seems my expectations are debatable.
// But I need to round up from 3+ decimal places so I expect "62.275" to become "6.28".
// The above example works in dollarFormat() but not numberFormat(). The ticket has other failing examples.

public string function roundedDollarFormat(
  required numeric amount,
  boolean roundUp = true
) {
  var scale = 10 ^ 2;
  var result = ( arguments.roundUp )
    ? round( arguments.amount * scale ) / scale
    : floor( arguments.amount * scale ) / scale;

  return dollarFormat( result );
}

rate = 782.14 + 62.275 - 472.00;

// Round up
writeDump( roundedDollarFormat( rate, true) );

// Round Down (No round)
writeDump( roundedDollarFormat( rate, false ) );
