WRPN Calculator


Windows Reverse Polish Notation (WRPN) is a public domain calculator that is modeled after the Hewlett-Packard HP-16c "Computer Scientist". This is not a Hewlett-Packard product. It is available for Microsoft Windows, Mac OS, Linux, and Android.

WRPN uses Reverse Polish Notation, which uses the ENTER key instead of the "=" (equals) key.

In addition to all the functions you'd expect from an ordinary calculator, WRPN also has many features specifically designed for the computer professional:
