jilabob: I agree, this is the best calculator I've ever used. I prefer it to my HP.
alexlube: This program does everything it says, and works great. I am an engineer, and while it doesn't completely replace my TI-89, it is nice to be able to work out some problems using my phone.
ledzepman: I am an engineering student and I have to say this program is incredible! Definently a must have for my 700p!BTW if anyone needs help with this program and it's features consult this web page http://easycalc.sourceforge.net/manual/manual.html
pranamd1: Lovely program. Why carry around my bulky TI-86 when my 680, less than half the size, can do everything it can do just as well? One minor annoyance: EasyCalc switches modes (i.e. from Basic to Scientific, from Scientific to Integer, etc.) every time I turn off the screen. Again, this is a minor annoyance, and not worth lowering my rating for this program, but it should be glanced at.
dperkins915: This is an awesome tool!! A must have for math classes...awesome!
abe: I love it, I´ve used for 5 years in my old IIIxe and now is in my Treo 700p
gliscameria: The best calculator ever. easily beats Ti-Anything. I've used this calculator for over 6 years now, and it got me through my physics degree, and is holding up just fine in grad school. It does integeration and solving extremely well. And if you're playing with hard functions, nothing beats graphing them and having a touch screen to find intercepts!
Absolutely the best calculator!
Side Note: IT DOES NOT REQUIRE MATHLIB. Just install the big PRC, it ran fine on my 650.
allgamer: The FREE Best Graphical Scientific, and multi caculator ever.
Must have for any student taking math courses.
v1.25
- Notes:
-
This release includes a new completely updated manual (also available as Plucker database) replacing the tutorial. There are a lot of additions and changes to the UI and the graph screen. List and Matrix manipulations are improved. See the Change Log for more details.
- Changes:
- New manual replaces the old tutorial.
- Manual also available as Plucker (www.plkr.org) database: EasyCalcManual.pdb.
- UI changes to make it more obvious which areas/buttons can be tapped.
- Major overhaul of graph setup form. Colors, axes labels, etc are now individually selectable.
- Change point line style to use small crosses instead of dots to increase visibility on HiRes screens.
- Deg/Rad/Grd setting respected for drawing and tracking polar graphs.
- Integer arithmetic is now signed.
- "Reduce Precision" preference defaults now to false.
- Many improvements in list/matrix use. See manual for details.
- round(), trunc(), ceil() and floor() now support complex numbers.
- 'if' statement now uses lazy evaluation, allowing recursive definitions.
- Check for stack overflow added during expression evaluation.
- Default stack size increased from 4 to 8K for PalmOS >= 3.0.
- Russian translation updated.
- Many bug fixes.
- adds hires and Dynamic Input Area (DIA) support to Easycalc.
- Hires support for Palm and Sony OS5 devices and Sony PalmOS 4 devices with HRLib. This included color icons, button images and graph plotting.
- DIA (Dynamic Input Area) support for Palm, Sony and Handera devices thanks to the PalmResize code from Alexander Pruss http://sourceforge.net/projects/palmresize).
- Added graph tracking for parametric functions.
- New resizable about form.
- Size of lists, databse items was stored as an Int16. Changed to UInt16. This increases the max list size to 4091.
- Added a lot of error checking for out of memory conditions.
- Changes to the build system (configure) to make all options available as configure options.
- Many bugfixes. See the file ChangeLog in the distribution or check the CVS history.
- Some bug fixes, some new features.
Features
Easycalc was a simple scientific calculator. You enter a formula, press the Execute button and you can read the result.
* Normal, Scientific and Engineering floating point mode
* All functions you would find on normal scientific calculator
* Unlimited number of variables and functions
* Graph support
* GuessIt function - it tries to find out, what the result means, like "pi/2", "e^(3/4)" and "47/23".
* Integer operations (unsigned 32bit), conversions between Bin/Oct/Oct/Hex
* Function solving through fzero' with three parameters - min,max and function, it solves the function (e.g. fzero(0:10:f()), where f()="x^2" will return '2'.). It is possible to write fzero(0:2:"(x-1)(x+1)") too.
* Up to 15 decimal points
* Scrollable results field
* Complex numbers, including a basic guessit for complexes
* Fast menu for selecting variables and functions
* Results history
* Normal/Polar/parameter graphs
* Tracing of functions in all modes
* Table mode for functions
* Installable version of EasyCalc with no graphs, you'll save about 20K of space, installable version with/without special functions
* Raffael added/improved many functions regarding some hard mathematics.
* Added popup-menu for built-in functions
* Some small changes to UI
* If you select the text and press a function button (e.g. sin), the selected text gets inserted into the function.
* Export to memopad. If you want import from memopad, write me, I'm not sure if it is a useful feature and I'll not add it until somone writes.
* Function/variable name can have letters 'G-Z' and numbers as part of their name
