FX-603PX 6.7.X07 Calculator
Programmable Scientific Calculator for Android.
Introduction
The FX-603PX is an Android emulation of the legendary Casio FX-603P and its printer and tape accessory. This emulator is based on the GNU Open Source Emulator FX-603P by Martin Krischik, but specifically optimized for high definition Android displays. It emulates almost exactly the functionalities of the original calculator and can be used as a full-featured programmable scientific calculator.
The FX-603PX supports all arithmetic, trigonometric, logarithmic, hyperbolic, statistical functions and all alphanumeric display options of the original calculator and last not least the FX-603PX 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 Android internal or external memory card for later use. Results can be printed out with the FP-10 thermal printer emulator and copied/pasted to other applications.Basic Features
- Arithmetic operations: Addition, Subtraction, Multiplication and Division, raising to Power and Root, Exponent, 33 parentheses at 11 levels and Constant operations.
- Scientific Functions: Trigonometric and Inverse Trigonometric functions (with angle in Degrees, Radians or Gradients), Hyperbolic and Inverse Hyperbolic functions, Logarithmic and Exponential functions. Factorial, Square Root, square, Decimal ⇔ Hour, Minute, Second conversion, Polar ⇔ Rectangular Coordinate conversion, Absolute value, Integer value, Fraction value, Percentage, Random numbers, π.
- Statistical functions: Standard Deviation (2 kinds), Mean, Sum, Square Sum, Number of Data.
- Memory: 5 key independent memory 110 register (non-volatile).
- Range of numbers: ± 1 × 10⁻⁹⁹ to ± 9.999999999 × 10⁹⁹ and 0, internal operations using 18 digits mantissa.
- Decimal Point: Full decimal floating point arithmetic with underflow (possible display of Engineering decimals).
- Calculation with Fractions: simple and mixed fractions
- Base-N (Binary, Octal, Decimal, Hexadecimal) calculations: Inverse, bitwise And, bitwise Or, bitwise Exclusive Or
Programming Features
- Number of Steps: 999 steps (non-volatile)
- Jumps: Unconditional jump (GOTO), up to 10 pairs, Condition jump (x=0, x≥0, x=F, x≥F), Count jump (ISZ=Increment And Skip If Zero), DSZ(Decrement And Skip If Zero), Subroutine (GSB) up to 9 subroutines, up to 9 depths.
- Number of Programs Storable: Up to 20 (P0 to P19)
- Checking and Editing Functions Check, Debug, Delete, Insert, etc.
- Indirect addressing for M-register, destination of jump, calling subroutines.
- Miscellaneous functions: Manual Jump (GOTO), temporary Suspension of execution (PAUSE), command code and step number displayed during check, simulated FA-6 adaptor, simulatord FP-40 printer.
Example Program to calculate Factorials
| Key-code | Comment |
|---|---|
| MODE2 | Change to mode 2 to enable editing of program areas P0 to P19 |
| P0 | From the program list, press P0 button to start editing the program area P0 |
| ALPHAn!=ALPHA | Output "n!=" in first row of display. Result will be shown in 2nd line |
| HLT | Waits for user input, user types in number and presses EXE button to continue program |
| Min00 | Stores the value typed in by the user in register M00 |
| 1 | Put 1 in current immediate register so there is a value to multiple with |
| LBL0 | Label for the loop |
| * | Multiply |
| MR00 | By n |
| DSZGOTO0 | Decrements M00 and back to LBL0 until M00=0 |
| = | End of loop, the machine has calculated 1*n*(n-1)*...*2*1=n! |
Manual and Program Library
The original Manual of the FX-603P can be downloaded here, together with the original Program Library of the FX-602P, it's predecessor which is fully backward compatible.
Demo Programs
Here are a few demo programs you can download and install on your Android device and open with the FX-603PX app (run as P0).
- Calculate Prime Factors of an Integer: primfa.pt
- Calculate Prime Numbers starting from an Integer: prime.pt
- Calculate Compound Interest from an Initial Capital over a number of Years: intrst.pt
- Calculate Factorial of an Integer: factor.pt
Missing Features
Currently VER, PEEK, POKE are not implemented.
