For students, engineers, scientists or people who fondly remember classic calculators, Halcyon Calc is a great application for manipulating numbers and even symbolic expressions.Features:- Use this calculator on an iPhone, iPod Touch or an iPad- Use your finger to quickly scroll through the stack to review intermediate results- Copy and paste support- Over 220 built-in operations, including trig, logarithms, real functions, complex operations and more- Allows you to work with real, complex and integer numbers.- Real and complex numbers can be displayed in standard, fixed, scientific and engineering format- Use over 120 built-in units to perform unit conversion or create your own units if the one you want is not already there- Integer numbers can be displayed in decimal, hexadecimal, octal and binary bases- Work with real and complex matrices and vectors.- Enter symbolic expressions and solve them for different values. Even better, solve quadratic formulas, find minima, maxima and roots of any expression.- Plot symbolic expressions in X/Y coordinates. Pan the coordinate space by dragging the plot in any direction. Zoom in and out using a pinch gesture.- Determine symbolic derivative, taylor series or numeric integral of an expression.- Store numbers, lists, strings and expressions in symbols. Create hierarchies of symbols to allow you to organize your calculations.- Create sequences of calculator commands into programs, creating your own operations which you can then include in expressions.- Store statistical data and calculate totals, averages, standard deviations, linear regressions, etc over that data.- Calculate the probabilities associated with standard distributions like the normal, F and T distributions.
