Calc4M

Updated 2009-06-04, now version 1.15

There are three versions, the original Calc4M that needs MIDP2.0 to run, a simplified Calc4M.m1 that runs on any Java mobile phone and a special .cod version for BlackBerrys. If you are unsure what to try, try the full version first and if it refuses to load, then try the simplified version

Download Calc4M.jar or Calc4M.jad, see also http://www.getjar.com/products/14794/Calc4M

If you have a BlackBerry, you may also try the .cod version at Calc4M.cod

If the above refuses to load, try the simplified Calc4Mm1.jar or Calc4Mm1.jad

Calc4M is a calculator for mobile phones. It works on phones with CLDC 1.0 and MIPD 2.0 which means most phones from 2004 and later, such as SonyEricsson K700 and Nokia 6230 and later. It is currently tested on SonyEricsson, Nokia, Samsung and Motorola platforms.

It is configurable and contains most of the normal functions such as trigonometric and logarithmic functions, conversions, constants, memories and binary and hexadecimal notation. The configurations include possibilities to

display a welcome screen or not
display the call stack or not
automatically return to the basic arithmetic screen or not
use full screen mode or not
use nice looking button texts or "safe" texts that works in any mobile
choose from two different keyboard layouts
select calculation font size
select default number format (sci/eng/default)
decide type of "long button press" notification

One important thing to note is that most buttons have two functions. Press and hold down the key to access the "secondary" function which is denoted by the bottom right text on the buttons.

If you have any comments, suggestions, feature requests or bug reports, just give me a note. I am also open for customizations according to specific needs, preferably if you are willing to pay for it :). Otherwise, it is free for normal use.
