Simple calculations

Use Natural Calculator in the daily calculations. It has standard set of arithmetic and algebraic operations.

All calculations are well understood by the fact that the calculator makes them in graphical form as on paper.

The main principle of Natural Calculator is What You See Is What You Calculate!

Trigonometry

Natural Calculator has built-in trigonometry, hyperbolic functions, and inverse them. It uses radians, degrees, grads as angle measure. The screenshots show using the trigonometric functions with scientific and complex numbers.

Variables and functions

Natural Calculator has many constants and functions for your convenience. Also, you can define your own variables and functions for using them in your calculations. See the examples in the screenshots.

With the help of own variables and functions you can easily deal with repetitive tasks. You can store them in a document, and use in everyday computing.

Solving of phisycal problems

Here is shown the solving of phisycal problems.

Using Natural Calculator to solve the problems is very simply and clearly. The program automatically selects the most appropriate phisycal unit, and you'll be able to translate the result in the desired one.

Unit conversion

Natural Calculator can convert the phisycal units within one system of measurement and between different unit systems.

Right-click on the result, click on "Units" and select the desired unit available at this time. Also easy to convert a unit to another system.

Complex numbers

Here are shown the computations using complex numbers.

Natural Calculator is fully supports complex numbers. It may be convert the result to three types: arithmetic, trigonometric and exponential. Following the mathematical rules, it displays result in all possible cases, bringing their braces.

Rational numbers

The screenshots are showing the calculations using rational numbers.

Natural Calculator can provide a solution in the form of ordinary fractions that may be useful for understanding the results of calculations.

Numeral systems

Natural Calculator can work with integer numbers. Here you see the calculations with different notations, logical operations and convesion between numeral systems.

It supports four basic number systems: binary, octal, decimal, hexadecimal. In order to present the results of calculations in a system, right click on it and select notation from menu.

Result accuracy

You can define the accuracy of the result for greater calculation precision. See the examples of this feature.

Right-click on the result and select accuracy from menu.

One formula window

For your convience Natural Calculator has a small window having one formula. It helps you in your simply daily calculations and takes up little space on your desktop.

Minimize the main window if you periodically need to take only one line. The window of one formula will always be on top of all windows and you will see the result. In doing so, it will not occupy much space.
