Descrição

For students, engineers, scientists or people who fondly remember classic calculators, Halcyon Calc Lite 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
- 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.
- 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.

HP 28S Calculator Replica

Just like the last reviewer, I had a HP 28S since 1989. It bit the dust last year. This is an exact replica! If you do not understand (RPN - Reverse Polish Notation) you will be confused like Phat Dude. Take some time to learn RPN, you will find it straight forward and easy to use.

Love the HP 28S

I've used my HP 28S for three decades. I'm thrilled to find an app that emulates this classic scientific calculator. I haven't used the app much yet, but I'm looking forward to testing its features.

I had the hp28s. This is a good replica

Pros: look and acts like the hp 28s.
Cons: free version is too locked down to tell how well it works. I would have like to tried out other features, but that requires at least 1 upgrade possibly more. I could not tell for sure. I would pass on this one since I cannot tell how well it will work.

Resposta do desenvolvedor ,

I appreciate the feedback and I am sorry you found the free version locked down. But I am wondering if perhaps there is a different problem. The free version is fully featured and I believe is quite functional without purchasing extra features. There are in-app purchases which unlock the following:

- A larger display which also removes in-app advertisement banners
- Unit conversion so you can convert feet to meters or any number of other units, including units you define yourself.
- Programming support so you can create your own custom actions and operations.
- The ability to create directories to store your own symbols in a hierarchical tree.

Those are the only restrictions in the free version. You can do basic calculations with real numbers, integers, complex numbers, vectors and matrices. You can enter equations, plot them, perform calculus on them, evaluate them for various values of variables.

Perhaps you were having a technical issue with the app which was preventing it from working for you and I am more than happy to work with you on that and help you to resolve it.
