Add different currencies in one calculation

Every amount you type can carry a currency tag. When you press =, Calcurate converts each tagged amount into your base currency at the current rate, then evaluates the whole expression with normal operator precedence (× and ÷ before + and −).

Example uses illustrative rates of 1 USD = 1.29 SGD and 1 USD = 7.12 RMB.

The breakdown line underneath shows each conversion, for example 120 USD ≈ 154.80 SGD · 300 RMB ≈ 54.35 SGD, so you can see exactly how the answer was built.

Tap a currency key after typing an amount (120 then USD) or before it (USD then 120). If you tagged the wrong one, tap another currency key straight away and the amount is retagged: 120 USD becomes 120 SGD in one tap.

Plain numbers act as plain numbers, so quantities and splits behave the way you expect.

Percent works like a desk calculator, which is what you want for tax, service charge, tips and discounts:

• 200 + 10% = 220 (add 10%)
• 200 − 15% = 170 (take 15% off)
• 80 × 25% = 20 (25% of 80)

With an answer on screen, tap a different base currency and the result is recalculated instantly. Tag a dinner bill with its currency (for example 2400 THB), then tap USD or SGD as the base to see what it means at home. Only tagged amounts are reconverted: plain numbers always count as the current base currency. Press an operator after = to carry the answer forward into the next calculation.

A row of up to three currency keys sits above the keypad (USD, SGD and RMB by default). Tap EDIT to choose any three of the 15 supported currencies. Each key shows a flag and its live rate against your base currency, such as 1 = 1.2900 SGD, so you get a rate check every time you look at the keypad.
