# approximate-pi

This program creates a bunch of points in a square, then draws a circle with the same radius. Then it checks which points are inside the circle. The ratio of inside to out should be around pi/4, therefor multiplying that by 4 should result in an approximation of pi.

## Run

- Run
`./cmake/approximate_pi`

## Build

- Run
`./scripts/build.sh`

## Results

```
787961 inside the circle, 212039 outside.
