Kalkulon

Kalkulon is a programmable expression calculator for programmers available for your Windows, Linux and Android device.

If you just need a simple calculator Kalkulon is probably not what you are looking for.

But if you are looking for a scientific calculator with the following features

* C-like syntax, e.g.: (0x10>>3)+(6|4)*7

* variables, e.g: bitmask = 0x0F0F; 0x1234&bitmask

* user defined formulas and scripts, e.g.: AddMul(a,b,c)=(a+b)*c; AddMul(1,2,3)

* fully programmable, e.g.: if, while, do, etc.

* result history (out, outl), e.g.: 3+4; out+8; outl[0]+outl[1]

* casts, e.g.: ((u8)-1)<<8

* dec, hex and bin number format, e.g.: (128+0x3d)&0b01101100

* strings and list, e.g.: list = {"Hallo ", "World"}; list[0]+list[1]

* syntax coloring for easy use of long expressions

* autoload file ("autoload.k") for user defined variables, formulas, programs

* GPL license

which can share formulas and scripts between your desktop and mobile device you should give Kalkulon a try.

For devices without hardware keyboard I recommend Hacker's Keyboard!

Details:

On the Android device the example and help files are automatically copied into "SDCARD/Kalkulon" folder on first start. This is also the working directory for Kalkulon. Put your Kalkulon scripts here, e.g. from your desktop PC.

The Exec() command works a little bit different on Android:

If the command is ACTION_EDIT or ACTION_VIEW, e.g.

Exec("ACTION_EDIT", "runregtest.k")

an Android Intent is sent to start an external Activity.

For all other commands a normal system() call is executed, e.g.

Exec("echo 1 > xxx") writes "1" into file "xxx" in Kalkulon folder.
