I don't know which is the most common way to calculate Pi in computer programs, but from the stochastics book a read for my recent stochastics exam, I have a randomized variation, which is quite cool I think.

The code example is included along with a bit of explanation for those not familiar with the concepts behind it. It uses two of PHP functions, pow() and mt_rand(), to run through a series of iterations and, using a preset precision value, find the "hits" to finally calculate the value at the end.

I want to release some Benchmark system can be uploaded to any web host and check how good the web hosting is. Pi (Ï') calculations spread widely as one of the most popular CPU benchmark system, that's why I have created a Pi calculator that can get to the accuracy you want. For now, there is still one thing I'm not sure yet, I will explain it after show you the code.

The function is provided (that takes in the precision value you want) and a brief explanation of what it does differently and a reason why to use it over the built-in function.
