A calculator with 3 computing modes in one application plus a handy scientific reference facility - different modes allow: 1) scientific calculations, 2) hex, oct & bin format calculations & 3) graphing applications:
1) Scientific Calculator mode includes:
* General Arithmetic Functions
* Trigonometric Functions - radians, degrees & gradients - including hyperbolic option
* Power & Root Functions
* Log Functions
* Modulus Function
* Random Number Functions
* Permutations (nPr) & Combinations (nCr)
* Highest Common Factor & Lowest Common Multiple
* Statistics Functions - Statistics Summary (returns the count (n), sum, product, sum of squares, minimum, maximum, median, mean, geometric mean, variance, coefficient of variation & standard deviation of a series of numbers), Bessel Functions, Beta Function, Beta Probability Density, Binomial Distribution, Chi-Squared Distribution, Confidence Interval, Digamma Function, Error Function, Exponential Density, Fisher F Density, Gamma Function, Gamma Probability Density, Hypergeometric Distribution, Normal Distribution, Poisson Distribution, Student T-Density & Weibull Distribution
* 20 Memory Registers
* Conversion Functions - covers all common units for distance, area, volume, weight, speed, pressure, energy, power, temperature, time, angles & 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
* The calculator can also be set to fractions mode for general arithmetic functions including use of parentheses, squares, cubes and their roots
2) HEX, OCT & BIN Calculator mode includes:
* Convert between hex, oct, bin & dec
* AND, OR, XOR, NOT, NAND, NOR & XNOR functions
* Left Hand & Right Hand Shift
* Power & Root Functions
* 20 Memory Registers
3) Graphing Calculator mode includes:
* General Arithmetic Functions
* Trigonometric Functions - radians, degrees & gradients - including hyperbolic option
* Power & Root Functions
* Logarithmic Functions
* Results table also available together with the graph
A default screen layout is available for each function showing all buttons on one screen or, alternatively, 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) - the output can be set to scroll either vertically (the default) or horizontally as preferred - 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 - move to SD for 2.2+ users
An extensive help facility is available which also includes some useful scientific reference 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.
This is an ad-supported app - an ad-free paid version is also available for a nominal US$ 0.99 but, as always, it's probably best to test the free version first before parting with your hard-earned cash :) - to download, please search for Scientific Calculator (adfree)
