A Rational Number is a number determined by ratio of some integer p to some nonzero natural number q. The set of rational numbers denoted Q, and represent the set of all possible integer-to -natural-number ratio p/q. In mathematical expressions unknown and unspecified rational numbers ar represented by lowercase, italicized letters from the late middle or end of the alphabet, especially r,s and i, and occasionally u through z. Rational Numbers are primarily of interest to theoreticians. Theoretical mathematics has potentially far-reaching applications in communications and computer science, especially in data encryption and security.
