Why do people say there is modulo bias when using a random number generator?

http://stackoverflow.com/questions/10984974/why-do-people-say-there-is-modulo-bias-when-using-a-random-number-generator

do people say there is modulo bias when using a random number generator I have seen this question.. help people understand why exactly there is modulo bias when using a random number generator like rand in C . c random.. but for a larger range this could skew the distribution biasing the smaller numbers. So when does rand n return a range of..

What is the optimal algorithm for generating an unbiased random integer within a range?
