All I can find is the decimal (3.14 blah blah blah) which is (obviously) not complete and precise. Online reference would be appreciated

Pi is an irrational number, so cannot be expressed as a fraction a/b where a and b are both integers.
3.14, 22/7 etc are just common approximations which serve a lot of maths, but for accurate working are not exact.

There is no fraction equal to pi, because pi is a transcendental number, what means that it is a real number, not a rational one. But there are good approximations like 355/113.

3 1/7 is not exact, but fairly close. Actually, I use 3.14159 for most of my calculations.
