Calccis vs my11c

Calccis is a reverse polish notation (RPN) calculator. It supports basic arithmetic, trigonometrical, logarithm and exponent calculations for real, fractional, and complex numbers. Degrees and radians can be used for trigonometrical functions. You can perform matrix calculations, too. There is an undo stack, which supports undoing and redoing the 100 latest operations. Calccis does not copy or mimic any existing physical calculators. However, the operation of the stack has been influenced by how the stack works in the 1990s Hewlett-Packard HP-48 family of calculators.

The scientific calculator that defined an era — now in your pocket. my11C brings the legendary 11C Voyager series scientific calculator back to life with cycle-accurate emulation running the original microcode. Every keystroke, every display flicker, every RPN operation — faithfully reproduced. WHY ENGINEERS LOVED THE 11C The 11C wasn't just a calculator — it was the trusted companion of engineers, scientists, and students throughout the 1980s. Its blend of powerful scientific functions, full programmability, and the legendary efficiency of RPN made it a desk-and-pocket classic. Decades later, it remains a benchmark of how a calculator should feel.
