Hi Kotlin community.

I am using “%.#”.format(number) to use only # decimal numbers to avoid display all decimal values, but this function returns with “comma” separator and I need this values with “dot” separator.

I have to use another function or I have to use a dependency to get the result.

Thanks

You probably want one of the overloads with a `Locale` parameter: [format](http://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/format.html)

Use `Locale.ENGLISH` or `Locale.ROOT`.
