Scientific Calculator (adfree) v2.4.4

Scientific Calculator (adfree) v2.4.4

Requirements: Android 1.6+
Overview: 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.

Please email any questions that are not answered in the help section or any requests for bug fixes, changes or extensions regarding the functions of the calculator – glad to help wherever possible.
