However pi = 3.1415....., cannot be written as a fraction and so has an infinite number of digits in any base. These are known as irrational numbers
Finally and strangest of all, irrational numbers are more common than rational numbers.
One more thing, there are 2 types of irrational numbers:
Algebraic such as the square root of 2 which can be found by simple algebra or can be formed by a compass and straight edge.
Trancendental numbers such as pi & e(base of the natural logarithms) which can't.
As for more irrationals, this is logical since any rational number can be multiplied by pi or e or both, or by 1/pi, 1/e, pi x e, pi/e, e/pi, or 1/(pi x e), not to mention such things as pi**n, e**n or their reciprocals.
