Calculator

The Calculator application included with Windows 2000 looks like those el cheapo pocket calculators that the bank gives you when you open an account. You can operate it by clicking the buttons with your mouse or by pressing the corresponding keys on your keyboard. Most of the buttons look just like the ones on the plastic calculator that's probably in your desk drawer at this very moment, but a couple require special explanation:

  • squrt. Finds the square root of the currently displayed number.

  • %. Type in one number, click this button, type a second number, and click this button again to find out what percentage the first number is of the second.

Tip

Without a paper-tape feature, it's easy to get lost in the middle of long calculations. The solution is simple: Type your calculation, such as 34+(56/3)+5676+(34*2)=, in a word processor. Highlight the calculation you've typed, choose EditCopy, switch to the Calculator, and then choose EditPaste. The previously typed numbers fly into the Calculator in sequence, finally producing the grand total on its screen. (You can then use the EditCopy command to copy the result back out of the Calculator, ready for pasting into another program.)

Choose ViewScientific, to turn this humble five-function calculator into a full-fledged scientific number cruncher, as shown in Figure 9-18.

After ducking into a phone booth, the mild-mannered Calculator (left) emerges as Scientific Calculator (right), which contains hexadecimal, decimal, octal, and binary modes and enough other intimidating buttons to impress almost anyone. To find out what a particular button does, right-click it and choose What's This? from the shortcut menu. Don't miss the online help, by the way, which reveals that you can control even the scientific mode from the key-board.
