Free dec software for pda

Scientific Calculator with trigonometric funcs, complex numbers, graphs, unlimited number of variables, degree/radian mode, HEX/OCT/BIN/DEC conversions and more.
You can work with number ranging from 1E-100 to 1E250, displaying them all with up to 15 decimal points.
Easycalc was a simple scientific calculator. You enter a formula, press the Execute button and you can read the result. This version includes:
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, youll 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, Im not sure if it is a useful feature and Ill not add it until somone writes.
Function/variable name can have letters G-Z and numbers as part of their name
Enhancements:
- Some bug fixes, some new featurs.

SC-102P is a powerful and freely available scientific calculator for the Palm platform.
Apart from scientific functions it alsooffers a full set of logical operations and conversions between differentnumeric systems (HEX, DEC, OCT, BIN).
Therefore, it is especially usefulfor computer engineers and programmers. The program is designed in a way, that it simulates the visual andoperational aspects of a true calculator, such that the user will beimmediately familiar with its interface.
The calculator program automatically adapts to single and multi color devices. The archive includes full documentation in english and german.
Main features:
- Fixed a serious bug concerning calculations with PI.
- Minor changes in appearance of user interface.

With the program SC-103PU you get a powerful and freely available scientific calculator for the Palm platform.

Apart from scientific functions it also offers a full set of logical operations and conversions between different numeric systems (HEX, DEC, OCT, BIN). Additionally the calculator offers a units mode for easy conversions between different units including currencies, as well as calculations with mixed units.

The program is designed in a way, that it simulates the visual and operational aspects of a true calculator, such that the user will be immediately familiar with its interface.

The calculator program automatically adapts to single and multi color devices. High resolution displays of SONY Clié devices and devices with Palm Operating System 5 and higher are automatically detected and supported.

Available in three different languages: English, German and Esperanto.
