Let us consider some examples of currency conversions:

In a U.S. locale, this displays:

1000.00000 10.00 $10.00 USD 10.00

4.2 Wrap up

We have covered lots of territory—alphabets, languages, dates, times, time

zones, numbers, money—and yet have only scratched the surface of what can

be done by combining these facilities. Internationalization is a brave new

world for software engineering, but with the proper tools it can be more

exciting than distressing.

const RWLocale& here = RWLocale::global();

double sawbuck = 1000.;

RWCString tenNone = here.moneyAsString(sawbuck, RWLocale::NONE);

RWCString tenLocal = here.moneyAsString(sawbuck,

RWLocale::LOCAL);

RWCString tenIntl = here.moneyAsString(sawbuck, RWLocale::INTL);

if (here.stringToMoney(tenNone, &sawbuck) &&

here.stringToMoney(tenLocal, &sawbuck) &&

here.stringToMoney(tenIntl, &sawbuck)) // verify conversion

cout << sawbuck << " " << tenNone << " "

<< tenLocal << " " << tenIntl << " " << endl;
