Randomized Pi calculation
Apr 02, 2007 @ 15:04:00

Since there is no "magic variable" to get a value for Pi in an application, Tobias Schlitt offers up the next best thing - his homegrown solution for creating the value (using a randomized variation).

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.

PHP: Calculate PI
Jan 25, 2007 @ 15:29:00

Mgccl let us know about a new bit of functionality he's worked up to calculate a higher precision value of Pi than the built-in PHP function can.

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, thatâ€™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.
