Surely ! Smile

Not quite! If you are interested only in the exact representation of the constant, than there is nothing more simple than \(\pi\) .

It looks like somehow I've failed to make myself clear this is all about original approximations to \(\pi\), not about exact formulas or other well known approximations. My bad.

The real thing

Just an approximation

Best regards,

Gerson.
