→The Monte Carlo Simulation (PI Calculation)
----
As this algorithm is based on random sampling, so there is only one function that does all the work.
Flat profile:
<pre>
Each sample counts as 0.01 seconds.
% cumulative self self total
time seconds seconds calls Ts/call Ts/call name
101.05 0.02 0.02 calculatePI(int, float*)
0.00 0.02 0.00 1 0.00 0.00 _GLOBAL__sub_I__Z11calculatePIiPf
</pre>
Call graph
<pre>
granularity: each sample hit covers 2 byte(s) for 0.47% of 2.11 seconds
