Calc Zero: Currency, a free currency conversion calculator

Calc Zero: Currency is a free member of the Calc Zero family, dedicated to currency calculations and conversions.

Calc Zero: Currency supports over 50 different currencies, with exchange rates updated several times a day. In addition to standard math operators, Calc Zero: Currency also can add and subtract user-settable tax and tip rates.

As with all Calc Zero apps, currency conversions are fast and easy. Enter the number, tap the currency to convert from, and tap the currency to convert to.

And as with all Calc Zero apps, fractions are fully supported, and the Equals key is optional (i.e., you can use RPN mode if you prefer).
