About 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.
