How would one handle arithmetics across different currencies?

[valeeum]

Is there a built-in mechanism for currency conversion arithmetics?

src_amount = '2306.56' // USD you need to convert var ratio = 1.23 ; // exchange ratio USD=>EUR var src = Money['USD']; var src_len = src.decimal_digits; var dst = Money['EUR']; var dst_len = dst.decimal_digits; var subunitDifference = src_len - dst_len; ratio = ratio / Math.pow(10, subunitDifference); var src_amt = Money.fromDecimal(src_amount, 'USD' , Math.ceil); var counterValue = src_amt.multiply(ratio, Math.ceil); var dst_amt = new Money(counterValue.getAmount(), 'EUR');

maybe we could add a CurrencyConverter implementation that would expose a method like this var currencyConverter = new CurrencyConverter(); var target = currencyConverter.convert(source, ratio);
