Andro11C is a HP 11C emulator for Android. It implements all features of the original calculator, including programming functions. It is available via Android's App Market.

Andro11C uses the same engine of the HP 11C Web emulator. It aims to mimic all features (and limitations) of the real device.

Characteristics

The emulator mimics the 11C calculator as closely as practically possible. It shares the same limitations as an original 11C: 399 programming steps, 20 memory positions etc.

Many emulators offer an ancilliary screen to query the contents of statistical registers and programming opcodes. Not this one :) The access interface is strictly the one you have in the real 11C.

Actually, if you find any discrepancies in relationship to a real unit, and they are not mentioned in following section, chances are you found a bug and I kindly ask you to report it.

Differences from real calculator

First of all, it is important to mention that the emulator engine does not use a ROM dump. It is a clean-room implementation. So the results simply can not guaranteed to be exactly equal.

The main interface deviation is the ON key, which toggles between decimal point and comma, and can't turn off the emulator.

Other known deviations:

• Calculations use 15-digit precision (related to C's double type), so there can be minor rounding differences in comparison to a real unit.
• Minus sign in LCD emulation looks different.
• Speed is obviously different; generally the emulator is much faster.
• You can use all programming steps and all STO positions at the same time, while in the real unit they share the same memory and there is a tradeoff.
• Footer elements like USER, RUN, PGRM etc. occupy different positions.
• Also, there is a slight augmentation in footer elements. For example, RUN shows the program step, STO-operation shows operation symbol and so on.
• Execution of programs may have a different speed and actual calculations are shown instead of "Running...".
• Random generation uses a different algorithm and does not use the seed.

Terms of use

The emulator is offered "as is". There are no guarantees of precision, exactness, or aplicability to any given purpose. The developer has no responsability for any damages incurring from usage of this software.
