R complex number i
Web2 Answers. Sorted by: 15. If a complex number z is written as z = a + b i, then Re ( z) = a and Im ( z) = b. (At risk of stating the obvious, "Re" stands for "Real" and "Im" stands for "Imaginary".) If we visualize complex numbers as vectors in R 2, Re is the projection onto the real axis, and Im is onto the imaginary axis.
