Thousands separator thymeleaf: use apostrophe

Question

I'm using thymeleaf to render my views. Is it possible to use ' (apostrophe) as a thousands seperator? Example: What I want is to replace WHITESPACE in the following example with a Value for an apostrophe.

<span th:text="${#numbers.formatDecimal(value, 5, 'WHITESPACE', 2, 'POINT' )}"

Is there a NumberPointType for apostrophe or another solution to achieve a formatting like this: 1'000.00

Answer 1

If you dig into the sourcecode of enum org.thymeleaf.util.NumberPointType you will see the only available options with standard #numbers.formatDecimal are..

public enum NumberPointType {
    POINT("POINT"),
    COMMA("COMMA"),
    WHITESPACE("WHITESPACE"),
    NONE("NONE"),
    DEFAULT("DEFAULT");
...

So my preference for you is to create a custom method inside your own code, for example as a bean or a utility object, and create your own function to format the decimal as you wish.

Update

public class UIutil {

/**
 * Formats a BigInteger to a thousand grouped String
 * @param number
 * @return
 */
public static String formatNumber (BigInteger number) {
    return String.format("%,d", number);
}

}

Assign:

context.setVariable("formatter", new UIutil());

Call:

th:text="${formatter.formatNumber(value)}"
