Here is a very interesting continued fraction expansion for pi/2 :

\pi/2=1+\cfrac{1}{1+\cfrac{1}{1/2+\cfrac{1}{1/3+\cfrac{1}{1/4+\cfrac{1}{1/5+\cfrac{1}{1/6+\cfrac{1}{1/7+\cfrac{1}{1/8+\cfrac{1}{1/9+\cfrac{1}{1/10+\cfrac{1}{1/11+\cfrac{1}{1/12+\cfrac{1}{1/13+\cfrac{1}{1/14+\cfrac{1}{1/15+\ddots}}}}}}}}}}}}}}} $$
