JRPN 16c

Programmer's calculator based on Emmet Gray's WRPN 16c, which simulates an HP 16c. This is an RPN-based calculator that works in floating point, and integers expressed in hex, decimal, octal or binary. I modified Emmet's WRPN (with permission) so that it uses rendered fonts for the keys. This makes them look nice and crisp on high resolution displays. I offer this software as-is, with no guarantee of any kind. The source is available on github. There's also a desktop Java version -- see https://jrpn.jovial.com/ for both.
