Mathf.Sin returning wrong value

Unity Engine
1

Hi guys (and girls),

I have one question about Mathf.Sin. When i put:

print(Mathf.Sin(Mathf.PI));

It return “-8.742278E-08”. Why? i supposed to return 0.

What im doing wrong?

That is 0, or close enough that it doesn’t make any difference. Floating point imprecision is the cause.
