Hi,
here is a tiny scientific calculator (binary = 95 K)
grpn-1.4.0-1 gtk+2 scientific calculator
http://lashwhip.com/grpn.html
(gtk+2 version updated from gtk+1.2 version 1.1.2)

GRPN is a graphical reverse polish notation (RPN) calculator. GRPN is written in C and uses the GIMP Toolkit (GTK) on top of X11. GRPN was developed under Linux but has also been tested under SunOS and Solaris. It should work with almost any UNIX, though.
GRPN works with real numbers and complex numbers. Numbers can be displayed in 4 different radix modes, and complex numbers can be displayed in either Cartesian or polar form.
GRPN uses a stack and reverse polish notation to evaluate expressions. The stack in GRPN is infinite and limited only by available memory.

the display digits might be set this way when running from command line:

Code: Select all

grpn -disp-fn "Liberation Mono Bold 16"

this could help to enhance visibility for poor eyesghted puppians (and so am I ...

)

I have tried the following command without success

Code: Select all

grpn -btn-fn "Liberation Mono Bold 16"

to set buttons font.

see

Code: Select all

grpn --help

for command line options.

buttons font may be set through Menu/Desktop/JWM configuration/Desktop/GTK theme and there by setting the desired font+size in the bellow-left "Font" field

last edited: to compile with default DEGREES setting:
edit /src/mode.c as follows: change line 32 from

Code: Select all

int radixMode = RADIANS;

to

Code: Select all

int radixMode = DEGREES;

That's all ...

; save and compile (just do make)[/code]
