Basic information formatting number as currency

[webserveis]

It would be interesting if it was delimited correctly depending on how the android device is configured and also if you want to show another type of currency. I hope it helps

Extract info decimal formater

        val nf: NumberFormat = NumberFormat.getCurrencyInstance(Locale.getDefault())

        if (nf is DecimalFormat) {
            val sym: DecimalFormatSymbols = nf.decimalFormatSymbols

            Log.d(TAG, "currency: " + sym.currency)
            Log.d(TAG, "currencySymbol: " + sym.currencySymbol)
            Log.d(TAG, "decimalSeparator: " + sym.decimalSeparator)
            Log.d(TAG, "digit: " + sym.digit)
            Log.d(TAG, "exponentSeparator: " + sym.exponentSeparator)
            Log.d(TAG, "groupingSeparator: " + sym.groupingSeparator)
            Log.d(TAG, "infinity: " + sym.infinity)
            Log.d(TAG, "internationalCurrencySymbol: " + sym.internationalCurrencySymbol)

@efguydan Do you want to check this?

Hello @webserveis, Thanks for the detailed comment. I am not sure I fully understand it though. The library currently allows you to configure a specific locale for it to use. It uses the device's locale if no locale was specified. It also allows you to configure a currency symbol to use.
