B4J Question Comma in Thousands e.g. £1,000.00?

[ElliotHC]

I need to add a comma in a label value when above 999, is this easy to do?

Just search for NumberFormat and NumberFormat2.

From the help, NumberFormat2 returns a String.
- 0 -> MinimumIntegers
- 3 -> MaximumFractions
- 2 -> MinimumFractions
- True -> GroupingUsed
Examples:
MyNumber Result
12.123456 12.123
12345.1 12,345.10
0.12 .12

(Not all regions separate thousands with a comma. So if your app targets more than the users that do that, you might want to use a smarter solution.)

Please post a few numbers as an example of the format you are looking for.

I had 'False' when I needed 'True' in NumberFormat2.
