FX-603P programable calculator

About this app

FX-603P Simulator is a very precise simulation of the classic FX-603P programmable calculator and all it's accessories. This simulation is not a toy but a full features simulations of almost functionality of the original calculator and it can be used as a full featured and fully programmable scientific calculator.

Used as a calculator the FX-603P simulator will exceed most other calculator available. The FX-603P simulator supports all arithmetic, trigonometric, logarithmic, hyperbolic, statistical functions and all alphanumeric display options of the original calculator.

And last not least the FX-603P simulator is fully programmable. You can write up to 20 programs, using 110 registers.

With the build in FA-6 cassette interface simulation you can save and load programs and data to your thump drive for later use. Or printout results with the FP-10 thermal printer simulation and then copy / paste them to other applications.

Do visit our FX-603P website or blog where you can download the original Manual of the Calculator. Remember that the Market-Comments have no answer function and I can't help you if you post there.

Ratings and reviews

High button latency, like .5 sec on my Pixel 4a. Is this intentional? Also I wish the labels for shift, 2nd, alpha and mode were always shown. Maybe enlarge the selected ones when the shift key is pressed. Otherwise this is awesome, saved me from buying a real one.

Thank you very much indeed. My fx502p can finally retire having lost most of its accessories over the decades. This is a fabulous app, which will save programs again with no need for overlays and cassette recorders! Brilliant .

Best of the best calculator in the android market. For Android ver13 there's a slight problem. When programing GSB P10 and above it doesn't write down or show the step. However surprisingly when exit the programing and view the program the step is registered .

What's new

Bug #20 x^(1/y) with x=0
Bug #21 Sezimal-Sexagesimal-conversion für -1>x>0
Bug #22 Rounding 0.99999…8 was to aggressive affecting all rounding operations ending on …998 - including just a single 8.
Bug #23: -12.4 [RND] [2] resulted in +12
Bug #24: Improve timings for executions and PAUSE to make the simulator speed more like the original.
