I'm using the Joda Money.class for currency in my project.
I'm using the NumberTool for formatting numbers inside a Velocity template.
context.put("number", new NumberTool());
I convert Money values into ints for placing these values inside a Velocity template.
example:
// 123435 €1234.35
priceInCents = price.getAmountMinorInt();
I want to format this value inside the Velocity template as below:
1.234,35
How do I accomplish this?
I tried the following cases:
$number.format('#0,00', $price) //Output: 1234,35
$number.format('#0.00', $price) //Output: 123435.00
$number.format('#00,00', $price) //Output: 12,34,35
$number.format('#00.00', $price) //Output: 123435.00
$number.format('#000,00', $price) //Output: 12,34,35
$number.format('#000.00', $price) //Output: 123435.00
So I found my answer. Make your own tool
context.put("currency", new CurrencyTool());
Usage:
$currency.format($price)
Basics created tool:
/**
* Tool for doing currency formatting
*/
@DefaultKey(value = "currency")
public final class CurrencyTool extends FormatConfig {
/**
* Constructor
*/
public CurrencyTool() {
}
/**
* @param money The {@link Money} object to format
* @return
*/
public String format(Money money) {
// Get the currency as an integer
final int value = money.getAmountMinorInt();
// Determine the units and cents
final int cents = value % 100;
String units = "" + (value / 100);
// Final formatted values
String formattedCents = "";
String formattedUnits = "";
// Format the cents to a 2 decimal number
formattedCents = cents < 10 ? "0" + cents : "" + cents;
// Format the units to parts of 3 separated with a dot
if (units.length() > 3) {
// units is above 999, formatting required
//Determine the length of the part that doesn't needs to be segmented
//example: 12 of 12345234 (12.345.234)
final int nonSegment = units.length() % 3;
formattedUnits = units.substring(0, nonSegment);
//place a dot for each segment
//example: nonSegment (dot) 345 (dot) 234
units = units.substring(nonSegment, units.length());
for (String segment : units.split("(?<=\\G...)")) {
formattedUnits = formattedUnits + "." + segment;
}
} else {
// units is below 1000, no formatting required
formattedUnits = units;
}
return formattedUnits + "," + formattedCents;
}
}
