Hi Guys,

Pi Calc is a little app that I whipped up for experimental reasons.

There are a few reasons to calculate Pi.
One is a benchmark, or speed test when running the same program across different platforms,
Another is to generate seemingly random numbers, or seeds for algorithms that produce
pseudo random numbers. Another reason is just for fun!


Installation:

Pi Calc is provided as a single eboot folder for 1.0 firmware PSP units, or many different
versions of DAX OE unofficial hybrid firmware commonly used by the PSP community to run
homebrew applications.
Copy the Pi Calc folder to the "GAME" or "GAME150" folder on your PSP memory stick, and you're
ready to go.

Usage:

Launch Pi Calc from the XMB Game menu, and shortly after, you will be prompted to press one
of four buttons. Their functions are self explianitory. Read the instructions on the screen.
You can calculate up to 30,000 digits of Pi with this version program, and see all the digits
scroll on the screen, but they are not saved in any way.
Once the screen is filled, and new lines on the screen are overwritten,
the printing is deliberately slowed down so the user can see what's going on.

The calculation is finished just before the printing begins.

The blue numbers allong the right margin indicate the digit number of Pi that is printed to
the left. This helps the user keep track of where the program is up to.

Credits:

The algorithm Pi Calc uses to calculate Pi is public domain, and I have long forgotten where
it came from, or who to credit. It was ported to the PSP by Art in July 2007.
There are many freely available Pi Calculation algorithms available on the internet.

Cheers, Art.
