Haxial Calculator for Mac

From Haxial Software:

Haxial Calculator is an advanced calculator that can evaluate complex expressions to practically any level of accuracy that you desire.

Other calculator programs blindly attempt to copy physical hand-held calculators by displaying buttons on the computer screen, and an appearance and function that closely mimicks a hand-held calculator. At Haxial, we believe this approach is fundamentally flawed. A computer is a far more powerful device than a hand-held calculator, and thus it is illogical and limiting to duplicate hand-held calculators on a computer. Haxial breaks out of this mindset by designing a calculator that takes full advantage of the fact that it is running on a fully-fledged computer.

With Haxial Calculator, instead of tediously clicking on little buttons, you can freely type a formula using the keyboard. For example, you can type a formula such as this into Haxial Calculator:

84 / (12 + (45 - 3.2)) * 1.24

Then press return, and Haxial Calculator interprets and evaluates the text you entered, and displays the answer. This free-form text editing of mathematical expressions is far superior to the tedious button-clicking of a hand-held calculator, or a calculator program that mimicks a hand-held calculator.

NOTE: The appearance of the user interface is customizable with skins/schemes. For more information, see http://www.haxial.com/appearance/
