Description

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 225 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, collect and expand factors and terms, 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.

Marvellous

I have bought about 6 calculators for ios, looking for a good HP RPN equivalent.
This is the best - its not just an emulator, but has been written from scratch to keep the great original features but improve them too, e.g. graph plotting at native resolution.

Works well with M1 Macs

Using this now in Monterey and it works like a charme. Even the Mac's keyboard is fully supported.
