phi = [1+sqrt(5)]/2
sqrt(5) is irrational and so phi is irrational.

They are all points on the [Real] number line.However, different irrational numbers: pi, sqrt(2), e, phi etc have different geometric applications.
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.
Pi is infinite & digits never end. 3.14159 are amongst the first. * * * * * The answer given above is for pi. The question was about phi - which is usually used to indicate the Golden Ratio! Like pi, phi is irrational - but unlike pi, is not transcendental. Phi = [1 + sqrt(5)]/2 = 1.61803 approx.
The golden number? Phi = 1.61803398872...
An irrational number.
