What exactly is Pi?

The Greek letter Pi [ ] is used, in mathematics, to symbolise the ratio of a circle's circumference to its diameter. It is commonly used to calculate the area of circles and the volume of cones and spheres.

The value of Pi is a constant and has been determined to be approximately 3.14159. For more accuracy, you can download a value of Pi calculated to 32 thousand decimal places.

The lower the calculation, the faster your PC.
