Natural Calculator

Natural Calculator is an easy and handy tool used for different mathematical computations.

Pros: Natural Calculator is a calculator that not only can calculate the normal operations of an ordinary pocket calculator but has additional computation facilities such as trigonometric function, hyperbolic functions. One is able to do these calculations in degrees and radians too. Logical functions are another useful set. It has a very simple user interaction mode. It looks like a piece of paper and one writes the calculation like one would on paper in A+B = form. The calculator calculates the result depending on the operator beside the equal sign. One can write up a page of calculations, edit as necessary with the cut and paste tools available. You could save the sequence of calculations for later use too. Number of significant digits and the calculation precisions are preset. Calculations can be done even when numbers are represented in any one of the scientific, integer, fraction, and complex formats. User variable and functions also can be integrated into the calculations. Units conversion is supported. In a formula written on paper, re-computation happens automatically when any component is changed. Can be integrated to mathematical programs via the clipboard.

Cons: Some messages are not very correctly worded and may cause a little confusion. Besides one need to be a little bit careful against the classical version 1.0 legends.

Overall: A simple application with a range(but limited) of calculations possible. Easy interface. Overall a good rated 3 star application.

Natural Calculator is a unique, powerful, and simple program for solving various mathematical tasks. Unlike any other such programs, Natural Calculator does calculations the same way you do them on paper. That’s because it uses conventional graphical mathematics syntax instead of string. Because Natural Calculator is an all-in-one solution to everything from everyday arithmetic to engineering solving, different people can use it for various jobs.
* Natural Calculator's on-screen interface is a blank on which you can enter text or mathematics expressions in handy graph view. The expressions are output the same as on paper.
* Results may have any predetermined number of digits and precision. You can define them for the whole document or for a separate expression.
* Computations can be performed with the following numbers: scientific, integer, rational, complex.
* Angular measure may be defined for a separate number, an expression result, or the whole document.
* There are built-in constants and functions.
* User variables and functions are useful. You can define them easily and use them in your computations. You can redefine built-in constants and functions also.
* Natural Calculator uses units of measurement. There are built-in and user units. You can define your own units or redefine existing ones. You can convert units within one unit system or from one to another system.
* The program uses handy automatic recompute on user input. Change a number or the value of a parameter and see what happens to your expressions and their results.
* There are two computation window types: standard multistring document and one-formula window.
* There is integration with mathematical programs that run formulas in string view through the clipboard.
* Natural Calculator uses include documents to use their variables, units, and functions.
* There is syntax highlight.
* Complete documentation is available.
