Natural Calculator 1.5

Natural Calculator is a unique, powerful and simple program to solve various mathematical tasks. Unlike any other such programs, Natural Calculator does calculations the same way you do it on the paper. That's because it uses conventional graphical mathematics syntax instead string-like one. Since this calculator is an all-in-one solution for everything, ranging from everyday arithmetic to engineering solving, it can easily be used for various types of jobs.

Major Features:

1. Natural Calculators on-screen interface is a blank on which you can enter text or mathematic expressions in handy graph view. The expressions are output as well as on paper.
2. Results may have any predetermined quantity of digits and precision. You can define them for the whole document or for a separate expression.
3. Computations can be performed with the following numbers: scientific, rational, complex.
4. Angular measure may be defined for separate number, expression result or the whole document.
5. There are built-in constants and functions. They are defined for different number notations.
6. User variables and functions are useful.
7. Natural Calculator uses units of measurement. There are build-in and user units. You can define your own units or redefine existing ones.
8. The program uses handy automatic recompute on user input.
9. There are two computation window types: standard multistring document and single formula window have been made for your usability.
10. There is the integration with mathematical programs that operate formulas in string view through clipboard.
11. Natural Calculator uses include documents for using their variables, units and functions.
12. Syntax highlight.
13. Complete documentation.
