Calculator
Like any computer, the Droid X includes a calculator. So the next time you need to find out the square root of 547 (it’s 23.388031, by the way), or simply figure out how much leave for a tip, you’re all set. Unfortunately, that’s about all it does. You can’t paste results from it into the Droid X clipboard. Still it’s a useful little app.
Launch it by tapping its icon from the Application Tray, and you see a basic, four-function calculator. Tap in an equation, like 67.5 x 32 =, and the answer appears at the top.
Note
The calculator doesn’t have the ability to store numbers into memory and recall them.
The Calculator does much more than basic math, though. You can also use it for more complex calculations such as sine, cosine, tangent, square root, and so on. To get to them, press the Menu key, and then choose “Advanced panel”. To get back to the basic panel, press the Return key, or press the Menu key and choose “Basic panel”.
Note
When you press the Menu key, you’ll notice a “Clear history” option. Given that the calculator doesn’t appear to maintain any numbers in memory, it doesn’t seem to serve a purpose. Maybe in some later version?
