Natural Calculator

Natural CalculatorNatural 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. Because Natural Calculator is all-in-one solution to everything from everyday arithmetic to engineering solving, it can be used by different people and 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 as well as on paper.
  • Results may have any predetermined quantity of digits and precision. You can define them for the whole document or for a separate expression. There are no limits upon significant digits, result accuracy or exponential threshold practically.
  • Computations can be performed with the following numbers: scientific (numbers has floating point with any precision), integer (binary, octal, decimal or hexadecimal notations), rational (result is a vulgar fraction), complex (result is present in arithmetic, trigonometric or exponential form).
  • Angular measure may be defined for separate number, expression result or the whole document.
  • There are built-in constants and functions. They are defined for different number notations. They may have maximum accuracy.
  • User variables and functions are useful. You can define them easily and use in your computations. You can redefine built-in constants and functions also.
  • Natural Calculator uses units of measurement. There are build-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. You can define your own unit systems and use their units in your job.
  • 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 single formula window have been made for your usability.
  • There is the integration with mathematical programs that operate formulas in string view through clipboard.
  • Natural Calculator uses include documents for using their variables, units and functions. Define your own symbols in document, save it, load in settings dialog, and use in a new document. Or, use supply documents with defined units, variables and functions.
  • Syntax highlight.
  • Complete documentation.
