## IntCalc for Mac OS X |
$0.99 |

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.
