<h1> Pi to an arbitary precision </h1>
|
|
|
|
Pi can be calculated by taking the arctangent of one
|
|
radian and multiplying it by four.
|
|
<p>
|
|
This php page
|
|
will pass the required precision to a bc script, and calculate
|
|
pi to as many places as you like.More than 10,000 places
|
|
may require a bit of a wait though....
