The golden number? Phi = 1.61803398872...
phi = [1+sqrt(5)]/2 sqrt(5) is irrational and so phi is irrational.

Tau gamma phi tenets number six?
Phi (fie) is the number 1.618033.... it is like pi but it is totally different numbers. They both never end.
phi
The value of phi is NOT 3.14. The value of phi, the Golden ratio, is [sqrt(5)+1]/2 which is approximately 1.62. It is an irrational number and so it has an infinitely long, non-recurring decimal representation.
the phi of n is the number of positive integers below n which do not share any factors with it. for example, the phi of 30 is 8 because it does not share any factors with 8 numbers: 1,7,11,13,17,19,23,29 these are called co-primes
The product of a whole number with a whole number is a whole number. A whole number is an integer ( a counting number).
