# I thought I found a way to compute PI, but I actually just found a super shitty way to print a variable.. const precision = 1000000 // convert degree to radians function rad(degree){ return degree * (Math.PI/180); } function calculatePI(){ // [x, y] // take first point on start of unic circle const point1 = [Math.cos(0) , Math.sin(0)]; // take second point at 0.001 degree const point2 = [Math.cos(rad(1/precision)), Math.sin(rad(1/precision))]; // Estimate 0.001 degree of circle const dist = Math.sqrt((point2[0] - point1[0] ) ** 2 + (point2[1] - point1[1]) ** 2); // Calculate full circle const perimeter = dist * precision * 180; return perimeter; } console.log(calculatePI());

The best way to find pi always starts by using Math.Pi

Pi is already encoded in sin and cos. It makes no sense to pass fractions of pi to sin/cos to calculate pi.

You could use the Leibniz formula instead:

```
calculatePI() {
return Math.PI;
}

console.log(calculatePI());
```

#include <math.h>

//<-----when you do not want to use: M_PI :-)

#define MATH_PI 4.0 * atan(1.0)

int main(){

printf("PI: %lf\n", MATH_PI);
