HP 10bii Calculator

This is a reproduction of the HP 10bii

Our design goal was to give users a clean 10bii that they could feel comfortable with immediately without the awkward additions found on other iOS implementations of this HP classic. Since CALC 1 contains so many tools for calculations, we did not need to add anything to the 10bii reproduction. We share the stack, TVM values and some storage registers so the user can switch between the 10bii and the many CALC 1 tools.

The examples and instructions in the HP manual will apply to this reproduction with these differences / enhancements:

How the 10bii fits in with CALC 1

Shared values

Sharing values allows you to use the 10bii to calculate a payment, then switch to the Amortization Form Calculator to generate a amortization table or graph without re-entering the values. This is just one example of the many tools available in CALC 1.

Shared Options

The CALC 1 options are read when the 10bii loads. So changes to the CALC 1 Options page while the 10bii is loaded (only on an iPad) will not be seen by the 10bii until it is loaded. Changes from the 10bii options (number of digits) will be copied from the 10bii to the CALC 1 settings when the 10bii is unloaded.

This calculator uses the first formula in Time Value of Money Compound Interest Formulas.
