[quote=Jorick] c/πd equals 1, and as such it is not a rational fraction that gives you pi, as they were discussing. Pro tip: if pi is in the fraction it's not rational and it probably won't equal pi.c = πdthusc/πd = πd/πd = 1[/quote] You do know that 1 WAS actually the answer that I was looking for... Congradulations Jorick you get a star for effort. *
