For students, engineers, scientists or people who fondly remember classic calculators, Halcyon Calc is a great application for manipulating numbers and even symbolic expressions.
- 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 200 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
- 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.
What's New in Version 2.0.1
Fixes a few bugs:
- Visit now works on symbols
- Improved cursor tracking to ensure the cursor is always visible when editing a very long entry
- The ISOL operation used to pop arguments off the stack even if the operation failed. Now, if ISOL fails, your arguments will still be on the stack.
My favorite RPN calculator
I went to college in the late 80's with an HP-28S. I still have the HP calculator, and it still works; and I'd been wanting an RPN calc for the phone that was similar to that one. There are a bunch of HP-12-like apps, but this is the first one I've found that behaves similar to the 28S. Very happy with Halcyon Calc; I've been able to delete all the other RPN calculator apps that I've tried.
