Fortran Monte Carlo to calculate pi via rejection sampling
Does what it says, probably pretty poorly.
Handles SIGINT gracefully, but required global variables, sorry.
Compile with gfortran: gfortran -o mcpi global.f90 MCPi.f90
Enter an integer for number of trials when prompted. Will break if you enter a float - maybe I'll fix that later (lol).
Example output:
The value of Pi calculated from 10000000 random points is: 3.14054
with relative error: 0.64872E-02
