How can I show a number with thousands seperators

It's not built into Etoys.

To find the right Squeak method, open a method finder. Give it an example, e.g. "12345. '12,345'". It will look for a method with that receiver giving that result.

(this works for methods with arguments, too. E.g. try "2. 3. 8")

Okay, Method Finder has to be the second coolest code tool ever.  I simply give an example of what I want to do and it finds it.

FYI to get to Method Finder: CMD-<comma> (CTRL-<comma> on PC, I think) -> open... -> method finder

Thanks Bert.

Well, the method finder works only if a single method does what you need, and there is no such method. One example that is helpful would be

        '1,000' . ',' . '1000'

or the less obvious

        '1,000' . $, . '1000'

(which uses Smalltalk's notation for characters)

I don't get the joke why you think any of the notations is inherently "better".

But maybe we can agree that mixing commas and dots is not ideal. Switching the notation based on locale is no solution either. Projects that use numerical strings would become dependent on the locale.

The best way I can think of is following the ISO recommendation of using spaces for digit grouping. This could be a relatively simple change, and would be unambiguous internationally.
