A Z -number, , has two components, Granular computing. Uncertain computing. 1. Introduction. In the real world, uncertainty is a pervasive phenomenon. Much of the information on which decisions are based is uncertain. They can be positive, negative, or zero. All rational numbers are real, but the converse is not true. Irrational numbers: Real numbers that are not rational. Imaginary numbers: Numbers that equal the product of a real number and the square root of −1. The number 0 is both real and purely imaginary.All complex numbers z = a + bi are a "complex" of just two parts: The real part: Re (z) = a. The imaginary part: Im (z) = b. When Re (z) = 0 we say that z is pure imaginary; when Im (z) = 0 we say that z is pure real . Both Re (z) and Im (z) are real numbers. Thus, any complex number can be pictured as an ordered pair of real numbers, (a, b) .1. There is no formal proof: it's a definition.
