Scientific Calculator (adfree) v2.4.5 for Android

Scientific Calculator (adfree) v2.4.5 Android apk app

Requirements: Android 1.6+
Overview: Scientific Calculator & Scientific Reference - good on both phones and tablets.

A calculator with 3 computing functions in one application plus a handy scientific reference facility - the following functions are included: 1) scientific calculations, 2) hex, oct & bin format calculations and 3) graphing applications. A default screen layout is available for each function showing all buttons on one screen and, in each case, all the functions are also available on a range of scrollable screens where the buttons are large enough for all finger types (but where the button size can also be adjusted if required) - a complete record of each calculation is stored in the calculation history, the result of which can be used in future calculations - a full range of settings allow easy customisation - an extensive help facility is available which also includes some useful scientific reference sections - the output can be set to scroll either vertically (the default) or horizontally as preferred - see the help facility for a full explanation of the options - move to SD for 2.2+ users


1) Scientific Calculator mode includes:

* General Arithmetic Functions
* Trigonometric Functions - both radians and degrees - including hyperbolic option
* Power and Root Functions
* Logarithmic Functions
* Modulus Function
* Permutation (nPr) and Combinations (nCr)
* Highest Common Factor, Lowest Common Multiple and Statistics Functions - the statistics function returns the count (n), sum, product, sum of squares, minimum, maximum, median, mean, geometric mean, variance and standard deviation of a series of numbers (please note that it's best to use vertical scrolling output for these functions)
* Conversion Functions - covering conversions of all common units for distance, area, volume, weight, speed, pressure, energy, power, temperature, time, angles and data size
* Constants - a wide range of inbuilt constants listed in 4 categories:
1) Physical & Astronomical Constants - press to include into a calculation or long press for more information on the constant and its relationship to other constants
2) Periodic Table - a full listing of the periodic table - press to input an element's atomic mass into a calculation or long press for more information on the chosen element
3) Solar System - press to input a planet's orbit distance into a calculation or long press for more information on the chosen planet
4) My Constants - a set of personal constants that can be added via the History
* In addition, the calculator can be set to fractions mode for general arithmetic functions

2) HEX, OCT and BIN Calculator mode includes:

* Conversion between hex, oct, bin and dec
* AND, OR, XOR, NOT, NAND, NOR & XNOR functions
* Power and Root Functions

3) Graphing Calculator mode includes:

* General Arithmetic Functions
* Trigonometric Functions - both radians and degrees - including hyperbolic option
* Power and Root Functions
* Logarithmic Functions
* Table of results also available together with the graph if required

The help function also includes sections covering names in the metric system, useful mathematical formulas and a detailed listing of physical laws containing a brief description of each law.

What's in this version:

27/8 (ver 2.4.4): added capability to add personal constants via the history - see the Constants section of the Help function for full details
05/9 (ver 2.4.5): 1) changed algorithm for LCM & HCF functions to allow large numbers to be used, 2) minor bug fixes and catches for potential input errors
