Description

A calculator with 6 computing modes in one application + a handy scientific reference facility - different modes allow: 1) scientific calculations, 2) hex, oct & bin format calculations, 3) graphing applications, 4) matrices, 5) quick formulas & 6) quick conversions:

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 - 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 including the ability to switch between portrait (the default) and landscape modes - move to SD for 2.2&
