Isn't pi exactly equal to 3 according to some old US law from the 1800's ???

I was quoting from the law that almost passed which started that
rumor. A circle-squarer decided he would get some publicity by having
the State of Illinois legislate in favor of his discovery, and he
figured the wy to do that was to offer them a way to save money by
doing so - in exchange for acknowledging his contribution to
mathematics, they would not have to pay royalties to include this new
geometrical truth in their school textbooks!

And this "truth" was that pi equalled 3 1/5.
