A pure imaginary number has a real part that is zero – that is, a = 0. So, a pure imaginary number has the form 0 + bi, or just bi. Another notation you may see is Re (z) = 0. Re (z) just means “the real part of the complex number z”. darlington local elections 2022WitrynaDescription. 1i returns the basic imaginary unit. i is equivalent to sqrt (-1).
