phi is a Greek letter commonly used in math and physics. It is pronounced "fee" and seen both capitalized and in lower case. In number there is a special function denoted by phi known as the Euler Phi-function.

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
In math, Phi, or the Golden ratio is approximatly 1.6180339887.Otherwise, Phi is how you pronounce a greek letter.
It is a real number, but it is not a whole number
The golden number? Phi = 1.61803398872...
It can be a real number which is not a rational number. That is, an irrational number such as sqrt(2), or cuberoot(5), or pi, or e, or phi. Or it can be a number that is not even a real number, such as a complex number or a quaternion.
It depends on what phi is being used for. Generally, phi is used to represent the Golden Ratio, [1+ sqrt(5)]/2. In that case phi is an irrational number approximately equal to 1.6180
phi = [1+sqrt(5)]/2 sqrt(5) is irrational and so phi is irrational.
Tau gamma phi
They are all points on the [Real] number line.However, different irrational numbers: pi, sqrt(2), e, phi etc have different geometric applications.

Protected health information (PHI) is defined as information that is individually identifiable that is collected by health care provider. That includes your phone number.
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.
