Calculate the rounding radius max value of a nSide object

Hi,
I'm searching how to calculate the rounding radius maximum value of a nSide object.
I tried with the following but it doesn't work:Float calculateSide(Int32 n, Float r) { Float theta, theta_in_radians; theta = 360 / n; theta_in_radians = theta * 3.14 / 180; return 2 * r * sin(theta_in_radians / 2); } Float max_rrad = calculateSide(n, r)/2;
Thanks

Assuming you mean a regular polygon, the maximum rounding radius is the same as the incircle of the polygon (as at this point all roundings touch and form a circle).
For formulas, see e.g.

Hi,
Thank you.Solution:
Float GeIncircle(Int32 n, Float r) { return r * cos(PI / n); } Float max_rrad = GeIncircle(n, r);
