DeskCalc is a simple calculator that nevertheless has some nice features that aren't apparent on first sight.

- DeskCalc understands much more than its simple keypad suggests.
  Besides the operators `+`, `-`, `*`, `/`, `%`, `^` and the constants `pi` and `e` the following math functions are supported:
  `acos`, `asin`, `atan`, `atan2`, `ceil`, `cos`, `cosh`, `exp`, `floor`, `log`, `log10`, `pow`, `sin`, `sinh`, `sqrt`, `tan`, `tanh`.

- When it comes to user input, DeskCalc is quite tolerant:
  `/`, `:`, `\` are all interpreted as division operators,
  `*`, `x` are valid symbols for multiplication.
  Also, be aware that `.` and `,` are both considered floating points, which means you mustn't use them as 1000 separators.

- Right-clicking offers these options:

  Auto Num Lock |  | automatically activates the number block when launching DeskCalc
  Audio Feedback |  | plays a sound when showing a result
  Show Keypad |  | hides the keypad when deactivated

- You can resize the calculator until it fits your needs and then put it as Replicant onto the Desktop via drag&drop of the symbol in the bottom right corner. Make sure Show Replicants is activated in the Deskbar.

- The keypad can be colored with a drag&drop from any color well, e.g. from Icon-O-Matic.

- You can move up and down in a history of past calculations with ↑↓.

- You can select DeskCalc's contents and drag&drop it into any application. Or you drop it into a Tracker window or onto the Desktop and a text file with that clipping is created there.

  Even better, the reverse is also possible:
  Create clippings as described at various stages of your calculation and go back to them by drag&dropping them back into DeskCalc.
  Or you drag&drop a calculation directly out of an email onto DeskCalc.

- DeskCalc can be used in Terminal. Just put the expression in double quotes, like this:

      ~> DeskCalc "sin(45)*(cos(12)+3.45)"
