Hey Luciano,
The formatting of decimal numbers is directly linked to the application language.
You can use functions such as formatDecimal to customize your output.
Depending on the situation, it may be necessary to replace , with . or vice versa, but this is not recommended.

You will need to use the formatDecimal function, not toString. For example...
formatDecimal(10560.69, '#,##0.00', 'pt-PT')

You can optionally specify the locale in the last parameter. If you want Portuguese, I think this is 'pt-PT'.
