MCPI

MCPI 0.9 (for PalmOS 3.x - 4.x - 5.x - 6.x)

This program estimates the value of PI by using a well known MonteCarlo Method. To run the simulation, type the number of cycles you want your Palm to use to estimate PI. The "Aristotle algorithm" is also included for comparison.

The final value may be quite different from the actual value of PI (3.14159). This is due to the fact that the random number generator is not completely random. We are not responsible for this, so consider this program only for educational - demo purpose, or as a benchmark.

Starting from version 0.9 a calculation time tracking is included; MCPI it can be reliably used as benchmark (some reference values will be available in the final 1.0 release).

This program is FREE.

Requirements:

Mathlib library needs to be installed. A copy of it is provided with the package.

Results in seconds. The calculation is performed using the Circle and Gauss method, for 1000 cycles.

The actual calculation is performed on the Palm Simulator/Emulator. Results obtained with real devices may vary.

History

(v. 0.9) Calculation time is now displayed. New user manual. Many minor bug fixed.
(v. 0.6) Aristotle algorithm added.
(v. 0.5) Averaged value of PI added. Icons are now properly displayed with OS5.
(v. 0.4) Deviation from the tab value added.
(v. 0.3.1) Minor bug fixed.
(v. 0.3) Choice of two possible algorithms (Gaussian or area of the circle). New tutorial.
(v. 0.2) The number of cycles is now unlimited. However if you run more than 10000 cycles, the simulation can take a long time. This may deplete the batteries of your PDA. Use with caution.
