Acron RPN Calculator


Don't let the simple interface fool you, this calculator is packed with features. Beautiful rendering of both the question and answer make your calculations virtually foolproof. Built in symbolic manipulation gives you the mathematically perfect answer to most common computations, with a fall back on 64 bit floating point approximations to handle the nastiest math. Supports integer calculations in binary, decimal, and hexadecimal for byte, word, dword, and qword integers.  Calculate one and two variable statistics with four available regression models.  Macros make it easy to repeat calculations without any programming skills.

There is also a free version of Acron RPN Calculator.  It has no ads, and never expires, but does have the following limitations:

  • Answers are always displayed as floating point. For instance, the full version knows that \(\sin \left ( 45^{\circ} \right )=\frac{\sqrt{2}}{2}\), but the free version only knows that it is 0.707106...
  • Functions that cannot use floating point numbers as input have been disabled. This includes factor, gcd, lcm, nPr, nCr, and all of the binary/decimal/hexidecimal integer functions.
  • Macros, in-line editing, and statistics are not available in the free version.
