Okay so Cartoon Calculator does all the things other scientific calculators do and has a big button screen for simpler maths. But what does it do that the others dont?
Well have you ever typed in a calculation and then thought: that cant be right. So you type it in all over again and then if the numbers dont match you have to type it in all over again to see which number was right. Nice way to impress the boss when you check your expenses in front of him. Never Again thanks to Cartoon Calculators spreadsheet like logging function. Just read the calculation and if you have mistyped anything change just that number.
Enhancements:
- Made it freeware. :-)
System requirements:
- StrongARM or XScale PocketPC, 4MB free

SciCalc by Jenkins features decimal, binary and hexadecimal display (with unique scrolling display for binary output), common mathematical formulae and engineering conversion routines as well as all common trigonometric, logarithmic and memory functions.

The conversions and formulae can be found in the integrated menu.

The main purpose of this program was to make a scientific calculator for the Palm PDA which could fit onto a single screen but be clear and easy enough for anybody who has used a standard scientific calculator in the past to use.

Added to this is the (optional) function to enter digits (in decimal, binary or hexadecimal) including the - sign to change polarity and the . decimal point using the PalmOS built-in "Graffiti" functions.

The ZIP version also includes the required MathLib library which is required to run this program.

This program is 100% compatible with non-colour Palm PDAs and has been fully tested on PalmIIIxe, PalmIIIc and PalmVx!

Screen Calculator is presently a fairly simple calculator that allows you to enter expressions in infix notation and see the results. In the near future, it will support named variables, scientific functions, graphics and maybe even programability.
Developers may be interested in the source (released under the GPL), which contains some useful routines for parsing and displaying floating point numbers.

(Note: This software is *developmental*. It may contain a few nasty bugs. Then again, it may not)

Enhancements:
- Correct the mistake of "Percent" function

SciCalc is a small Scientific Calculator for Handhelds.

It does not allow for "Intermediate or Chain Calculations", i.e., you can not perform the following without pressing the equal sign after each operation:

Example: "3 * 2 * 4 + 5 = " IS NOT Allowed.
You must operate on the expression as follows: " 3 * 2 = 6 * 4 = 24 + 5 =29 "

You will notice that the * ; / ; + and - operators are un-enabled after one is pressed and that the " = " blinks.
So you must select the " = " sign to finish the current operation prior to moving on to the next.

As the fire of the Calmarian sun began to fade, Styli civilization faced imminent destruction...until an eleventh hour scientific breakthrough allowed the Styli to capture pieces of the dying sun and place them into orbs which could be used to heat the tiny planet they inhabited. All was well for eons...
Then, a coalition of their enemies launched a surprise attack on the planet and stole most of the orbs. If they are not recovered quickly, the Styli civilization is done for! Every available space warrior has been mustered and they race towards their retreating enemies.....
