Atari Calculator CX8102#

the Atari Calculator is an advanced non-programmable as well as programmable calculator that supports RPN, ALG and ALGN calculation modes. Calculator goes far beyond the limits of Atari Basic’s mathematical capabilities, precision and has no bugs. Calculator has 100 memory registers, additionally a 42 number stack and is fully programmable up to 3072 bytes. Programs and memory registers can each be stored separately on disk or tape. It was the 'Mathematica', 'Maple', Mathcad' etc. of its time.

FEATURES OF THE ATARI CALCULATOR:#

Built in 145 functions often used in science and finance
The ability of hardcopy output using any of the ATARI printers
The ability to save and load numerical data from disk or tape
You can define whether to use standard input or RPN (Reverse Polish Notation). RPN is generally preferred in scientific work
Easy conversion between Imperial/Metric systems: (Fahrenheit-Celsius, Degrees-Radians, Polar-Rectangular, etc.)
Memory with displayable stack (you can see what's in memory)
You have the ability to fix the amount of digits displayed to 8 places and also exponentiation
The capability to easily enter numbers in Decimal, Octal, or Hex.
The standard math functions of Pi, square root, rounding off, reciprocals, etc.
Fundamental functions (absolute value function, fraction function, integer function, truncate function, etc.)
Algebraic and trigonometric functions, statistics functions, financial functions, bit manipulation functions, etc.
Algebraic functions including factorials, modulos, logarithm's
Sine, Cosine, Tangent functions, and the Arc's of each
Statistical functions with slope, mean functions, standard deviation, and much more including linear regression
Financial applications with 14 different functions
much more to explore...

The Calculator requires 24K of RAM.

Please do not use MEM.SAV with DOS. Instead use the SAVEM as well as the LOADM command of Calculator to store and load the user memory to other programs and/or devices.

In the content pages (page vii to xii in the manual or page 5 to 10 in the PDF-file) it is possible through a click on the line to directly jump to the desired page. The same is true for the index (page 187 to 190 in the manual or page 197 to 200 in the PDF-file). With the back button in Adobe Reader a direct jump from the desired page back to the content or index page is possible.
