Your loop both starts and stops at this single line, because you end it
with the semicolon...

What use is an if statement without any following action?
Besides, never, never test for equality when working with floating point
numbers. Round-off errors might bite real hard.
if (theta2 > 91.0) do_something();
or
if (theta2 > (90.0 + eps)) do_something();
