Hi, I have seen two slightly different definitions for the Euler's phi function. They don't cause any difference in its value but I was just wondering if there would be anyone who would complain about the use of one or the other?
One says that for a positive integer n, phi(n) is the number of positive integers less than n and relatively prime to it. The other differs slightly by saying that it's the number of positive integers less than or equal to n and relatively prime to it. Because n is not relatively prime to itself this doesn't make a difference in its value and using "less than or equals" seems slightly superfluous, however, I am writing a report and I just want to be very precise about the whole thing. Thanks for your help.
