Calculor has two parts: the equation and the answer.

The Menu

Calculor has a context menu - to use it, right-click on the window!

Resizing Calculor

You can resize the equation by just sizing the window.

To resize the answer you hold shift whilst resizing.

But you can use the keyboard too.

ctrl+resize for the equation,

shift+ctrl+resize for the answer.

If you forget, just look in the Calc Menu!

Basic Math

•You can use parenthesis ( ).

•Use the * for multiplication.

•There is syntax colouring for easy-reading.

Quick and Easy Real-Time Editing

You can edit the equation in real time on the fly

Press Enter to replace the equation with the answer, or from the Calc Menu, choose Set Answer.

•If you select part of your equation and choose Evaluate Selection, it will calculate just that part and replace just that part of the equation with its answer, then it will recalculate the whole

In the System Tray of your taskbar you will find Calculor's Tray Icon. If you click on this icon it will show or hide Calculor. It also has a little menu with a few tidbits from Calculor's context menu.

To minimize Calculor you can either push the Escape Key, use the Minimize button in the Title Bar, click on the Tray icon or use the Minimize to Tray option in Calculor's menu.

Due to limitations in the compiling software, Calculor cannot process a number higher than 2**64-1, which is: 9223372036854775800 on a 64bit system

but on a 32bit system it is 2**32-1, which is: 4294967295. If you reach that value, it just stops computing - that is, it just stops updating the answer. But that is a pretty extraordinary number, so hopefully it won't be a problem for you. Just so you realize that.

Uh, also, Calculor is pretty complicated under the hood, so if you enter really elaborate, unexpected combinations of numbers and symbols and letters, you may get some pretty interesting answers.
