What's New!
Version 7 has included the following:
- Added a new "auto-scale" font system
- Added a configuration option to change the display font (or set to 0 for auto-scaling)
- Added copy-n-paste via the keyboard
- Windows version has a "Check for Updates" feature
Release Notes
A "point release" (a change to the number at the first decimal place) normally indicates that a change to the config file is also required.
Since there is no formal notification process for changes, users are encouraged to periodically view this page.

Technical Considerations
There are quite a few differences between this software implementation and the original (physical) HP 16C calculator
- Floating point values have more precision/range than the real calculator. The real calculator uses 56-bit BCD floating point, whereas this version uses 64-bit "IEEE 754" Double. So, this means that the floating point overflow and underflow conditions will not match the real calculator. (Page 56)
- Values in the stack and storage registers are (optionally) synchronized when switching between the Integer and Floating Point modes. Use the SyncConversions property in the configuration file to enable/disable this feature. In the real calculator, registers are untouched, the stack is wiped, and the X and Y registers contained values that are left overs from converting the X value. (Page 56)
- The number of storage registers and program memory do not compete for the same amount of memory. Use the NumRegisters and PrgmMemoryLines properties in the configuration file to set these arbitrary limits. The real calculator had 203 bytes of memory available for use between registers and program lines. (Page 62)
- The behavior of widening/narrowing the word size of registers does not follow the physical calculator behavior (Page 67)
- There is no limit to a program's level of subroutine nesting. The real calculator had a limit of 4. (Page 95)
- Since the display can hold up to 35 digits, there is no need for Windowing and Scrolling in any mode other than Binary (Page 33). In the Binary mode, there is only Window 0 (the left) and Window 1 (the right).
- The keys on this calculator do not support key repeat or key hold functions. Consequently functions such as Show {HEX, DEC, OCT, BIN}, MEM, and STATUS display their message for a short period of time, and then revert back to the original screen values. (Pages 29, 37, and 65)
- The ON button doesn't do anything. The real calculator uses the ON button for several functions such as: change decimal separator, reset continuous memory, etc. (Pages 20, 61, and 106). Use the normal File/Exit menu item or the close button to exit the application
- The calculator "state" (analogous to the "continuous memory" feature of the real calculator) uses a text-based XML file for storage. The initial power on defaults are not the same as the real calculator, but you can edit the CalcState.xml file to match, if you like.

Currently Not Implemented:
- The Index register does not have a word size of 68 (Page 68)
