For some reason when I input Math.PI and 3.14 I get completely different and even impossible results
Edit: Nevermind, I'm just dumb and didn't notice the e-16
It gives ~10^-16 something very close to zero you can
console.log(Math.sin(Math.PI).toFixed(2))Here I have set up a test of your problem
console.log(Math.sin(3.14));
console.log(Math.sin(Math.PI));When run, I get this result:
0.0015926529164868282
1.2246467991473532e-16
The 2nd number is a really really small positive number. It is essentially 0. The first number is slightly larger, but 3.14 is a rounded value of PI, and that's why you get the difference
