[ ] Choice 3: pi = 3 [needs legislature of Indiana approval] Attempts to legislate pi are always questionable, and when you ask a majority of uninformed voters[3] to choose between items, it's natural for the compromise to win, and not unheard of for it to end up "3".Funny thing is that pi=3 was the "official" value taught in Japanese schools in the last few years when pupils were introduced to the value, since it was considered that decimal numbers were too complex... This has been reverted last year if I remember well.
Decimals will not help you in determining the "official" value of pi. pi is transcendental and thus irrational and connot be written with a finite number of decimals. If you only need an approximation, then you have to choose your approximation according to your need. For some calculation the value 3 might be sufficient.
