GRPN is a graphical reverse polish notation (RPN) calculator. It 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 is written in C and uses the GIMP Toolkit (GTK) on top of X11.
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.
GRPN supports the following functions:
· General Math Functions: + - * / sqrt sqr pow neg
· Exponential and Logarithmic Functions: log alog exp ln
· Trigonometric Functions: sin asin cos acos tan atan
Both keyboard and mouse operation are fully supported. GRPN can also cut and paste data to/from other X11 applications.
