DownloadRPN Calculator is a simple but powerful RPN calculator for MacOS with a scalable interface via selectable function palettes.


RPN Calculator is a simple but powerful RPN calculator for MacOS with a scalable interface via selectable function palettes.
This calculator is one of the only mac calculator programs that handles complex arithmetic.
Here are some key features of "RPN Calculator":
A simple interface aimed at fitting in with the rest of the Mac OS
Multiple levels of interface complexity, revealing only the features needed
A few interface goodies, including contextual menus where useful
Smart copy & paste (concerning complex number recognition)
Drag & drop almost everywhere
8 to 4096 element stack, with 8 visible elements at all times
8 memories with mouseover preview of contents
Adequate set of builtin scientific functions
Special functions, such as Bessel functions
Full complex number support with respect to the applicable builtin functions
Numerous keyboard shortcuts
A compact mode which leaves only the display visible
Arbitrary number of userdefined constants
Arbitrary number of userdefined functions of up to 10 variables
Base conversion between bases ranging from 2 to 36
Unit conversion
Statistics registers with most common statistical functions
Linear systems of up to degree 5
Determinants and inverses (up to 5 by 5)
Prime number search
Factorization and prime factorization
Rational number approximation to decimal expansions
Extended dynamic range where appropriate via Victor Shoup's NTL
Ability to log events during a single session.
What's New:
Rebuilt with RB5.5.4. This should eliminate the "CPU hog" problem seen in Mac OS 10.3.x. Stack drop places a zero at the top instead of duplicating the top element.
