What is CalcFX?

CalcFX is a new powerful scientific calculator, runs on all kind of platforms (e.g. desktop, web and mobile) and has no function keys that need difficult operation. You can input math expressions directly, without needing to learn the key layout, key combinations and difficult variable operations as you can name them freely. Unlimited calculation history can be seen anytime, and copied very quickly from a user friendly GUI.

CalcFX supports features as follows.

• Mathmatical expression input directly
• Function
• Variable
• Constant Number
• Many Operators
• Unlimited Calculation History
• Quick Copy

The facilities previously mentioned reveal that this application gives a richer calculation environment.
