Direct Scientific Calculator

Powerful Scientific Calculator, variables, functions, integrals, calc history

Direct Calc offers for FREE all the stuff people usually need so much:

- simple yet functional interface

- predictable behavior

- calculation history

- large set of functions

- ability to create your own components (variables and functions)

- ability to save/restore calculation flow.

- ability to expand functionality by loading custom templates

- no Ads and no disturbing stuff, just tool for efficient work

Scientific Calculator computes math expressions of any difficulty, showing them in preview window as formatted together with result while typing new symbols.

Straightforward predictable behavior - what you see is what you get!

You can create your own Variables and Functions, and use them in further calculations. There are system (predefined) Constants as well.

Calculation Session can be saved in text document to be restored later. Document is compatible with Dysolve application.

Easy to use interface. Swipe DOWN on the calculator panel - and Calculation History appears, swipe RIGHT for Component Manager activity, swipe LEFT for Document Save/Load activity, swipe UP for app Settings activity.

Calculator is powered by Dysolve Math Solver engine, which has proved itself as a robust and efficient tool for solving wide range of math and engineering problems.

Two high-quality appearance themes: Native (dark) and Arctic (light).

On the worksheet you can:

- Compute mathematical expressions, using a wide range of standard and special math functions.

- Define Variables - constant or depending on other variables.

- Define Functions - with any number of arguments. Functions then can be plotted or used in calculations.

- Define piecewise-continuous Functions (when function has several continuous definitions on different intervals).

- Add single-line comments to create a comprehensive calculation report.

- Compute definite integrals.

- Compute Limits of a functions.
