Compare the performance of your Android mobile by calculating the Pi number

Calculating the number Pi

Pi is an irrational number. We usually know it as 3.14. If you have worked with it, you may have specified 3.1416. Although we all know that it is no longer an approximation. In fact, being an irrational number, has infinite decimal numbers. Today we know how to calculate the decimals of Pi, but we need a processor take care of these calculations to make it really useful. For example, a mobile is capable of calculating 8 thousand digits of Pi in less than 1 tenth of a second. Of course, depending on the mobile, it will be more or less fast when doing the calculation to obtain the decimals of Pi. And that is why calculating the Pi number can be a good way to measure and compare the performance of our Android phones.

Comparing the performance of the Android mobile

With the Super Pi application, you can use your mobile to calculate the Pi number. Obviously, for you it is really useless. Nobody uses a Pi number with so many digits. However, it can be useful. Depending on the time it takes the mobile to calculate the number Pi, we can compare the performance of our Android mobile. We have 8 options to perform the calculation. The application lets us choose if we want to calculate a number of 8 thousand bits, 16 thousand bits, 32 thousand bits… and so on up to 4 million bits, 4 million decimal places. My cellphone it took about 77 seconds to perform this last calculation.

If you like math, and you want compare the performance of various mobiles, it can be a curious way to do it. Super Pi is a completely simple free application. It is not complex at all. Nor is it a benchmark with which we can determine an extremely precise value of how the mobile performs in different areas, but it is a very easy way to make a curious measurement with which to compare different mobiles and laugh at our friend’s mobile.
