DeskCalc

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:

  Enable Num Lock on start up		automatically activates the number block when launching DeskCalc
  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 ↑ and ↓.

• 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)"
