Assignment 1

Findings

The code used is taken from the following site http://www.cplusplus.com/forum/beginner/1149/ with some changes to the code.

This program will calculate pi to a precision based on the value entered by the user. Currently it displays to a precision of 9 decimal places.

Will attempt to figure out a way to calculate to as much decimal places as possible, which should drastically increase the time it takes to run the program. Currrent possible solution is to use the BigNumber library.

(Updated)

The code used is taken from the following site https://helloacm.com/cc-coding-exercise-finding-approximation-of-pi-using-monto-carlo-algorithm/ with some changes to it.

This program will calculate pi using the Monte Carlo approach to a precision based on the value entered by the user.

Value of 1 Million

Value of 10 Million

Value of 100 Million

Value of 1 Billion

Assignment 2 and 3

I have combined the 2nd and 3rd part of the assignment together, since I had some issues with the kernel.

The following results compares the upgraded code with the original to show a significant increase in speed.

(Note) For some reason the code crashes my graphic driver past 8000000 (8 million) dots, and even at 8 million it crashes half the time.
