The golden number? Phi = 1.61803398872...
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
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.

An example of a valid mobile phone number might be +1 417 555-0123, except with an actual mobile phone number instead of the fictitious 555-0123. An example in the UK would be +44 7700 900123, which is the (fictitious) UK mobile number 07700 900123 written in international format. A valid mobile phone number is a real phone number that actually connects to a working mobile phone.
Oh, dude, a daytime phone number is just a phone number you can call during the day, you know, when the sun is out and all that. An example could be like 555-123-4567, but like, who actually calls during the day anymore? I mean, we have texting and stuff now, right?
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.
Yes. For example, if you multiply the square root of 2 (an irrational number) by itself, the answer is 2 (a rational number). The golden ratio (Phi, approx. 1.618) multiplied by (1/Phi) (both irrational numbers) equals 1 (rational). However, this is not necessarily true for all irrational numbers.

No, the devil's phone number is not real. Many associate the numbers 666 with the devil.
