An RPN calculator, loosely based on the ancient HP16 programmer's calculator.

It can display and switch between any of the common number bases, and therefore can serve as a hex calculator, or hexadecimal conversion calculator, a hex to decimal calculator,an octal to hexidecimal converter, etc.

Features include:

Displays all four elements of the stack with room to see all 32 bits in binary mode.

Each element can be individually displayed in any of binary, octal, decimal, hexadecimal, or ASCII.

An optional drawer allows you to see any stack element in two number bases at once.

Many bitwise integer functions ("and", "or", "not", shift, rotate, etc.).

Floating-point functionality includes square root, reciprocal, y-to-the-x, and trigonometric and logarithmic functions.


Release Notes:

Fixed an issue on El Capitan.

Review by gadget King

works great & cheap! - It is a RPN calculator that is cheap & works great. I think the previous reviewer is not familiar with RPN calculators. I like regular ones better but for certain math, it is the only way. I needed to do math in hex & also some in decimal jumping back & forth in the process. Worked perfect.

Lacking in so many ways - Layout is bad, missing serious functions like AND/OR/XOR. Works with Catalina is about all i can say.
