from the website:
|
||
|
|
|
||
|
|
The whole idea behind this application is to use the same Pi calculation
|
||
|
|
algorithm on every Android Device and check how fast that proccess is.
|
||
|
|
Better calculation times, conclude to faster Android devices. This way you
|
||
|
|
can also check how lightweight your custom made Android build is. Or not.
|
||
|
|
|
||
|
|
As Pi is an irrational number, Benchmark Pi does not calculate the actual Pi
|
||
|
|
number, but an approximation near the first digits of Pi over the same
|
||
|
|
calculation circles the algorithms needs.
|
||
|
|
|
||
|
|
So, the number you are getting in miliseconds is the time your mobile device
|
||
|
|
takes to run and complete the Pi calculation algorithm resulting in a
|
||
|
|
approximation of the first Pi digits.
